always wrapped with jQuery or jqLite; they are never\n * raw DOM references.\n *\n * ## Angular's jQuery lite provides the following methods:\n *\n * - [addClass()](http://api.jquery.com/addClass/)\n * - [after()](http://api.jquery.com/after/)\n * - [append()](http://api.jquery.com/append/)\n * - [attr()](http://api.jquery.com/attr/)\n * - [bind()](http://api.jquery.com/bind/) - Does not support namespaces\n * - [children()](http://api.jquery.com/children/) - Does not support selectors\n * - [clone()](http://api.jquery.com/clone/)\n * - [contents()](http://api.jquery.com/contents/)\n * - [css()](http://api.jquery.com/css/)\n * - [data()](http://api.jquery.com/data/)\n * - [eq()](http://api.jquery.com/eq/)\n * - [find()](http://api.jquery.com/find/) - Limited to lookups by tag name\n * - [hasClass()](http://api.jquery.com/hasClass/)\n * - [html()](http://api.jquery.com/html/)\n * - [next()](http://api.jquery.com/next/) - Does not support selectors\n * - [parent()](http://api.jquery.com/parent/) - Does not support selectors\n * - [prepend()](http://api.jquery.com/prepend/)\n * - [prop()](http://api.jquery.com/prop/)\n * - [ready()](http://api.jquery.com/ready/)\n * - [remove()](http://api.jquery.com/remove/)\n * - [removeAttr()](http://api.jquery.com/removeAttr/)\n * - [removeClass()](http://api.jquery.com/removeClass/)\n * - [removeData()](http://api.jquery.com/removeData/)\n * - [replaceWith()](http://api.jquery.com/replaceWith/)\n * - [text()](http://api.jquery.com/text/)\n * - [toggleClass()](http://api.jquery.com/toggleClass/)\n * - [triggerHandler()](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.\n * - [unbind()](http://api.jquery.com/unbind/) - Does not support namespaces\n * - [val()](http://api.jquery.com/val/)\n * - [wrap()](http://api.jquery.com/wrap/)\n *\n * ## In addition to the above, Angular provides additional methods to both jQuery and jQuery lite:\n *\n * - `controller(name)` - retrieves the controller of the current element or its parent. By default\n *   retrieves controller associated with the `ngController` directive. If `name` is provided as\n *   camelCase directive name, then the controller for this directive will be retrieved (e.g.\n *   `'ngModel'`).\n * - `injector()` - retrieves the injector of the current element or its parent.\n * - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current\n *   element or its parent.\n * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top\n *   parent element is reached.\n *\n * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.\n * @returns {Object} jQuery object.\n */\n\nvar jqCache = JQLite.cache = {},\n    jqName = JQLite.expando = 'ng-' + new Date().getTime(),\n    jqId = 1,\n    addEventListenerFn = (window.document.addEventListener\n      ?

The ngAnimate directive will automatically extract the duration\n * of the animation to determine when the animation ends. Once the animation is over then both CSS classes will be\n * removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end\n * immediately resulting in a DOM element that is at it's final state. This final state is when the DOM element\n * has no CSS transition/animation classes surrounding it.\n *\n * <h2>JavaScript-defined Animations</h2>\n * In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations to browsers that do not\n * yet support them, then you can make use of JavaScript animations defined inside of your AngularJS module.\n *\n * <pre>\n * var ngModule = angular.module('YourApp', []);\n * ngModule.animation('animate-enter', function() {\n *   return {\n *     setup : function(element) {\n *       //prepare the element for animation\n *       element.css({ 'opacity': 0 });\n *       var memo = \"...\"; //this value is passed to the start function\n *       return memo;\n *     },\n *     start : function(element, done, memo) {\n *       //start the animation\n *       element.animate({\n *         'opacity' : 1\n *       }, function() {\n *         //call when the animation is complete\n *         done()\n *       });\n *     }\n *   }\n * });\n * </pre>\n *\n * As you can see, the JavaScript code follows a similar template to the CSS3 animations. Once defined, the animation\n * can be used in the same way with the ngAnimate attribute. Keep in mind that, when using JavaScript-enabled\n * animations, ngAnimate will also add in the same CSS classes that CSS-enabled animations do (even if you're not using\n * CSS animations) to animated the element, but it will not attempt to find any CSS3 transition or animation duration/delay values.\n * It will instead close off the animation once the provided done function is executed. So it's important that you\n * make sure your animations remember to fire off the done function once the animations are complete.\n *\n * @param {expression} ngAnimate Used to configure the DOM manipulation animations.\n *\n */\n\nvar $AnimatorProvider = function() {\n  var NG_ANIMATE_CONTROLLER = '$ngAnimateController';\n  var rootAnimateController = {running:true};\n\n  this.$get = ['$animation', '$window', '$sniffer', '$rootElement', '$rootScope',\n      function($animation, $window, $sniffer, $rootElement, $rootScope) {\n    $rootElement.data(NG_ANIMATE_CONTROLLER, rootAnimateController);\n\n    /**\n     * @ngdoc function\n     * @name ng.$animator\n     * @function\n     *\n     * @description\n     * The $animator.create service provides the DOM manipulation API which is decorated with animations.\n     *\n     * @param {Scope} scope the scope for the ng-animate.\n     * @param {Attributes} attr the attributes object which contains the ngAnimate key / value pair.

The payoff\n * comes in the way of\n * [guarantees that promise and deferred APIs make](https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md).\n *\n * Additionally the promise api allows for composition that is very hard to do with the\n * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.\n * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the\n * section on serial or parallel joining of promises.\n *\n *\n * # The Deferred API\n *\n * A new instance of deferred is constructed by calling `$q.defer()`.\n *\n * The purpose of the deferred object is to expose the associated Promise instance as well as APIs\n * that can be used for signaling the successful or unsuccessful completion of the task.\n *\n * **Methods**\n *\n * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection\n *   constructed via `$q.reject`, the promise will be rejected instead.\n * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to\n *   resolving it with a rejection constructed via `$q.reject`.\n *\n * **Properties**\n *\n * - promise – `{Promise}` – promise object associated with this deferred.\n *\n *\n * # The Promise API\n *\n * A new promise instance is created when a deferred instance is created and can be retrieved by\n * calling `deferred.promise`.\n *\n * The purpose of the promise object is to allow for interested parties to get access to the result\n * of the deferred task when it completes.\n *\n * **Methods**\n *\n * - `then(successCallback, errorCallback)` – regardless of when the promise was or will be resolved\n *   or rejected calls one of the success or error callbacks asynchronously as soon as the result\n *   is available. The callbacks are called with a single argument the result or rejection reason.\n *\n *   This method *returns a new promise* which is resolved or rejected via the return value of the\n *   `successCallback` or `errorCallback`.\n *\n * - `always(callback)` – allows you to observe either the fulfillment or rejection of a promise,\n *   but to do so without modifying the final value. This is useful to release resources or do some\n *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full\n *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for\n *   more information.\n *\n * # Chaining promises\n *\n * Because calling `then` api of a promise returns a new derived promise, it is easily possible\n * to create a chain of promises:\n *\n * <pre>\n *   promiseB = promiseA.then(function(result) {\n *     return result + 1;\n *   });\n *\n *   // promiseB will be resolved immediately after promiseA is resolved and its value will be\n *   // the result of promiseA incremented by 1\n * </pre>\n *\n * It is possible to create chains of any length and since a promise can be resolved with another\n * promise (which will defer its resolution further), it is possible to pause/defer resolution of\n * the promises at any point in the chain. This makes it possible to implement powerful apis like\n * $http's response interceptors.\n *\n *\n * # Differences between Kris Kowal's Q and $q\n *\n *  There are three main differences:\n *\n * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation\n *   mechanism in angular, which means faster propagation of resolution or rejection into your\n *   models and avoiding unnecessary browser repaints, which would result in flickering UI.\n * - $q promises are recognized by the templating engine in angular, which means that in templates\n *   you can treat promises attached to a scope as if they were the resulting values.\n * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains\n *   all the important functionality needed for common async tasks.\n *\n *  # Testing\n *\n *  <pre>\n *    it('should simulate promise', inject(function($q, $rootScope) {\n *      var deferred = $q.defer();\n *      var promise = deferred.promise;\n *      var resolvedValue;\n *\n *      promise.then(function(value) { resolvedValue = value;

While for simple usage patterns this doesn't matter much, for advanced usage\n     * it is important to familiarize yourself with these APIs and the guarantees they provide.\n     *\n     *\n     * # General usage\n     * The `$http` service is a function which takes a single argument — a configuration object —\n     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}\n     * with two $http specific methods: `success` and `error`.\n     *\n     * <pre>\n     *   $http({method: 'GET', url: '/someUrl'}).\n     *     success(function(data, status, headers, config) {\n     *       // this callback will be called asynchronously\n     *       // when the response is available\n     *     }).\n     *     error(function(data, status, headers, config) {\n     *       // called asynchronously if an error occurs\n     *       // or server returns response with an error status.\n     *     });\n     * </pre>\n     *\n     * Since the returned value of calling the $http function is a `promise`, you can also use\n     * the `then` method to register callbacks, and these callbacks will receive a single argument –\n     * an object representing the response. See the API signature and type info below for more\n     * details.\n     *\n     * A response status code between 200 and 299 is considered a success status and\n     * will result in the success callback being called. Note that if the response is a redirect,\n     * XMLHttpRequest will transparently follow it, meaning that the error callback will not be\n     * called for such responses.\n     *\n     * # Shortcut methods\n     *\n     * Since all invocations of the $http service require passing in an HTTP method and URL, and\n     * POST/PUT requests require request data to be provided as well, shortcut methods\n     * were created:\n     *\n     * <pre>\n     *   $http.get('/someUrl').success(successCallback);\n     *   $http.post('/someUrl', data).success(successCallback);\n     * </pre>\n     *\n     * Complete list of shortcut methods:\n     *\n     * - {@link ng.$http#get $http.get}\n     * - {@link ng.$http#head $http.head}\n     * - {@link ng.$http#post $http.post}\n     * - {@link ng.$http#put $http.put}\n     * - {@link ng.$http#delete $http.delete}\n     * - {@link ng.$http#jsonp $http.jsonp}\n     *\n     *\n     * # Setting HTTP Headers\n     *\n     * The $http service will automatically add certain HTTP headers to all requests. These defaults\n     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration\n     * object, which currently contains this default configuration:\n     *\n     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):\n     *   - `Accept: application/json, text/plain, * / *`\n     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)\n     *   - `Content-Type: application/json`\n     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)\n     *   - `Content-Type: application/json`\n     *\n     * To add or overwrite these defaults, simply add or remove a property from these configuration\n     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object\n     * with the lowercased HTTP method name as the key, e.g.\n     * `$httpProvider.defaults.headers.get['My-Header']='value'`.\n     *\n     * Additionally, the defaults can be set at runtime via the `$http.defaults` object in the same\n     * fashion.\n     *\n     *\n     * # Transforming Requests and Responses\n     *\n     * Both requests and responses can be transformed using transform functions. By default, Angular\n     * applies these transformations:\n     *\n     * Request transformations:\n     *\n     * - If the `data` property of the request configuration object contains an object, serialize it into\n     *   JSON format.\n     *\n     * Response transformations:\n     *\n     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).\n     *  - If JSON response is detected, deserialize it using a JSON parser.\n     *\n     * To globally augment or override the default transforms, modify the `$httpProvider.defaults.transformRequest` and\n     * `$httpProvider.defaults.transformResponse` properties. These properties are by default an\n     * array of transform functions, which allows you to `push` or `unshift` a new transformation function into the\n     * transformation chain. You can also decide to completely override any default transformations by assigning your\n     * transformation functions to these properties directly without the array wrapper.\n     *\n     * Similarly, to locally override the request/response transforms, augment the `transformRequest` and/or\n     * `transformResponse` properties of the configuration object passed into `$http`.\n     *\n     *\n     * # Caching\n     *\n     * To enable caching, set the configuration property `cache` to `true`. When the cache is\n     * enabled, `$http` stores the response from the server in local cache. Next time the\n     * response is served from the cache without sending a request to the server.\n     *\n     * Note that even if the response is served from cache, delivery of the data is asynchronous in\n     * the same way that real requests are.\n     *\n     * If there are multiple GET requests for the same URL that should be cached using the same\n     * cache, but the cache is not populated yet, only one request to the server will be made and\n     * the remaining requests will be fulfilled using the response from the first request.\n     *\n     * A custom default cache built with $cacheFactory can be provided in $http.defaults.cache.\n     * To skip it, set configuration property `cache` to `false`.\n     *\n     *\n     * # Interceptors\n     *\n     * Before you start creating interceptors, be sure to understand the\n     * {@link ng.$q $q and deferred/promise APIs}.\n     *\n     * For purposes of global error handling, authentication, or any kind of synchronous or\n     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be\n     * able to intercept requests before they are handed to the server and\n     * responses before they are handed over to the application code that\n     * initiated these requests.

The function needs to return the `config` directly or as a\n     *     promise.\n     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or resolved\n     *      with a rejection.\n     *   * `response`: interceptors get called with http `response` object.

To\n     * counter this your server can prefix all JSON requests with following string `\")]}',\\n\"`.\n     * Angular will automatically strip the prefix before processing it as JSON.\n     *\n     * For example if your server needs to return:\n     * <pre>\n     * ['one','two']\n     * </pre>\n     *\n     * which is vulnerable to attack, your server can return:\n     * <pre>\n     * )]}',\n     * ['one','two']\n     * </pre>\n     *\n     * Angular will strip the prefix, before processing the JSON.\n     *\n     *\n     * ## Cross Site Request Forgery (XSRF) Protection\n     *\n     * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which\n     * an unauthorized site can gain your user's private data. Angular provides a mechanism\n     * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie\n     * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only\n     * JavaScript that runs on your domain could read the cookie, your server can be assured that\n     * the XHR came from JavaScript running on your domain. The header will not be set for\n     * cross-domain requests.\n     *\n     * To take advantage of this, your server needs to set a token in a JavaScript readable session\n     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the\n     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure\n     * that only JavaScript running on your domain could have sent the request. The token must be\n     * unique for each user and must be verifiable by the server (to prevent the JavaScript from making\n     * up its own tokens).

This means that the outer form is valid when all of the child\n * forms are valid as well. However browsers do not allow nesting of `<form>` elements, for this\n * reason angular provides {@link ng.directive:ngForm `ngForm`} alias\n * which behaves identical to `<form>` but allows form nesting.\n *\n *\n * # CSS classes\n *  - `ng-valid` Is set if the form is valid.\n *  - `ng-invalid` Is set if the form is invalid.\n *  - `ng-pristine` Is set if the form is pristine.\n *  - `ng-dirty` Is set if the form is dirty.\n *\n *\n * # Submitting a form and preventing default action\n *\n * Since the role of forms in client-side Angular applications is different than in classical\n * roundtrip apps, it is desirable for the browser not to translate the form submission into a full\n * page reload that sends the data to the server. Instead some javascript logic should be triggered\n * to handle the form submission in application specific way.\n *\n * For this reason, Angular prevents the default action (form submission to the server) unless the\n * `<form>` element has an `action` attribute specified.\n *\n * You can use one of the following two ways to specify what javascript method should be called when\n * a form is submitted:\n *\n * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element\n * - {@link ng.directive:ngClick ngClick} directive on the first\n  *  button or input field of type submit (input[type=submit])\n *\n * To prevent double execution of the handler, use only one of ngSubmit or ngClick directives. This\n * is because of the following form submission rules coming from the html spec:\n *\n * - If a form has only one input field then hitting enter in this field triggers form submit\n * (`ngSubmit`)\n * - if a form has has 2+ input fields and no buttons or input[type=submit] then hitting enter\n * doesn't trigger submit\n * - if a form has one or more input fields and one or more buttons or input[type=submit] then\n * hitting enter in any of the input fields will trigger the click handler on the *first* button or\n * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)\n *\n * @param {string=} name Name of the form.

Use this\n * directive to avoid the undesirable flicker effect caused by the html template display.\n *\n * The directive can be applied to the `<body>` element, but typically a fine-grained application is\n * preferred in order to benefit from progressive rendering of the browser view.\n *\n * `ngCloak` works in cooperation with a css rule that is embedded within `angular.js` and\n *  `angular.min.js` files. Following is the css rule:\n *\n * <pre>\n * [ng\\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {\n *   display: none;\n * }\n * </pre>\n *\n * When this css rule is loaded by the browser, all html elements (including their children) that\n * are tagged with the `ng-cloak` directive are hidden. When Angular comes across this directive\n * during the compilation of the template it deletes the `ngCloak` element attribute, which\n * makes the compiled element visible.\n *\n * For the best result, `angular.js` script must be loaded in the head section of the html file;\n * alternatively, the css rule (above) must be included in the external stylesheet of the\n * application.\n *\n * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they\n * cannot match the `[ng\\:cloak]` selector. To work around this limitation, you must add the css\n * class `ngCloak` in addition to `ngCloak` directive as shown in the example below.\n *\n * @element ANY\n *\n * @example\n   <doc:example>\n     <doc:source>\n        <div id=\"template1\" ng-cloak>{{ 'hello' }}</div>\n        <div id=\"template2\" ng-cloak class=\"ng-cloak\">{{ 'hello IE7' }}</div>\n     </doc:source>\n     <doc:scenario>\n       it('should remove the template directive and css class', function() {\n         expect(element('.doc-example-live #template1').attr('ng-cloak')).\n           not().toBeDefined();\n         expect(element('.doc-example-live #template2').attr('ng-cloak')).\n           not().toBeDefined();\n       });\n     </doc:scenario>\n   </doc:example>\n *\n */\nvar ngCloakDirective = ngDirective({\n  compile: function(element, attr) {\n    attr.$set('ngCloak', undefined);\n    element.removeClass('ng-cloak');\n  }\n});\n\n/**\n * @ngdoc directive\n * @name ng.directive:ngController\n *\n * @description\n * The `ngController` directive assigns behavior to a scope. This is a key aspect of how angular\n * supports the principles behind the Model-View-Controller design pattern.\n *\n * MVC components in angular:\n *\n * * Model — The Model is data in scope properties; scopes are attached to the DOM.\n * * View — The template (HTML with data bindings) is rendered into the View.\n * * Controller — The `ngController` directive specifies a Controller class; the class has\n *   methods that typically express the business logic behind the application.\n *\n * Note that an alternative way to define controllers is via the {@link ng.$route $route} service.\n *\n * @element ANY\n * @scope\n * @param {expression} ngController Name of a globally accessible constructor function or an\n *     {@link guide/expression expression} that on the current scope evaluates to a\n *     constructor function. The controller instance can further be published into the scope\n *     by adding `as localName` the controller name attribute.\n *\n * @example\n * Here is a simple form for editing user contact information. Adding, removing, clearing, and\n * greeting are methods declared on the controller (see source tab). These methods can\n * easily be called from the angular markup. Notice that the scope becomes the `this` for the\n * controller's instance. This allows for easy access to the view data from the controller. Also\n * notice that any changes to the data are automatically reflected in the View without the need\n * for a manual update. The example is included in two different declaration styles based on\n * your style preferences.\n   <doc:example>\n     <doc:source>\n      <script>\n        function SettingsController() {\n

In other words, if the expression assigned to **ngIf evaluates to a false\n * value** then **the element is removed from the DOM** and **if true** then **a clone of the\n * element is reinserted into the DOM**.\n *\n * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the\n * element in the DOM rather than changing its visibility via the `display` css property.  A common\n * case when this difference is significant is when using css selectors that rely on an element's\n * position within the DOM (HTML), such as the `:first-child` or `:last-child` pseudo-classes.\n *\n * Note that **when an element is removed using ngIf its scope is destroyed** and **a new scope\n * is created when the element is restored**.  The scope created within `ngIf` inherits from\n * its parent scope using\n * {@link https://github.com/angular/angular.js/wiki/The-Nuances-of-Scope-Prototypal-Inheritance prototypal inheritance}.\n * An important implication of this is if `ngModel` is used within `ngIf` to bind to\n * a javascript primitive defined in the parent scope. In this case any modifications made to the\n * variable within the child scope will override (hide) the value in the parent scope.\n *\n * Also, `ngIf` recreates elements using their compiled state. An example scenario of this behavior\n * is if an element's class attribute is directly modified after it's compiled, using something like\n * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element\n * the added class will be lost because the original compiled state is used to regenerate the element.\n *\n * Additionally, you can provide animations via the ngAnimate attribute to animate the **enter**\n * and **leave** effects.\n *\n * @animations\n * enter - happens just after the ngIf contents change and a new DOM element is created and injected into the ngIf container\n * leave - happens just before the ngIf contents are removed from the DOM\n *\n * @element ANY\n * @scope\n * @param {expression} ngIf If the {@link guide/expression expression} is falsy then\n *     the element is removed from the DOM tree (HTML).\n *\n * @example\n  <example animations=\"true\">\n    <file name=\"index.html\">\n      Click me: <input type=\"checkbox\" ng-model=\"checked\" ng-init=\"checked=true\" /><br/>\n      Show when checked:\n      <span ng-if=\"checked\" ng-animate=\"'example'\">\n        I'm removed when the checkbox is unchecked.\n      </span>\n    </file>\n    <file name=\"animations.css\">\n      .example-leave, .example-enter {\n        -webkit-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;\n        -moz-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;\n        -ms-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;\n        -o-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;\n        transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;\n      }\n\n      .example-enter {\n        opacity:0;\n      }\n      .example-enter.example-enter-active {\n        opacity:1;\n      }\n\n      .example-leave {\n        opacity:1;\n      }\n      .example-leave.example-leave-active {\n        opacity:0;\n      }\n    </file>\n  </example>\n */\nvar ngIfDirective = ['$animator', function($animator) {\n  return {\n    transclude: 'element',\n    priority: 1000,\n    terminal: true,\n    restrict: 'A',\n    compile: function (element, attr, transclude) {\n      return function ($scope, $element, $attr) {\n        var animate = $animator($scope, $attr);\n        var childElement, childScope;\n        $scope.$watch($attr.ngIf, function ngIfWatchAction(value) {\n          if (childElement) {\n            animate.leave(childElement);\n            childElement = undefined;\n          }\n          if (childScope) {\n            childScope.$destroy();\n            childScope = undefined;\n          }\n          if (toBoolean(value)) {\n            childScope = $scope.$new();\n            transclude(childScope, function (clone) {\n              childElement = clone;\n              animate.enter(clone, $element.parent(), $element);\n            });\n          }\n        });\n      }\n    }\n  }\n}];\n\n/**\n * @ngdoc directive\n * @name ng.directive:ngInclude\n * @restrict ECA\n *\n * @description\n * Fetches, compiles and includes an external HTML fragment.\n *\n * Keep in mind that Same Origin Policy applies to included resources\n * (e.g. ngInclude won't work for cross-domain requests on all browsers and for\n *  file:// access on some browsers).\n *\n * Additionally, you can also provide animations via the ngAnimate attribute to animate the **enter**\n * and **leave** effects.\n *\n * @animations\n * enter - happens just after the ngInclude contents change and a new DOM element is created and injected into the ngInclude container\n * leave - happens just after the ngInclude contents change and just before the former contents are removed from the DOM\n *\n * @scope\n *\n * @param {string} ngInclude|src angular expression evaluating to URL.

You configure ngPluralize directive\n * by specifying the mappings between\n * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html\n * plural categories} and the strings to be displayed.\n *\n * # Plural categories and explicit number rules\n * There are two\n * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html\n * plural categories} in Angular's default en-US locale: \"one\" and \"other\".\n *\n * While a plural category may match many numbers (for example, in en-US locale, \"other\" can match\n * any number that is not 1), an explicit number rule can only match one number. For example, the\n * explicit number rule for \"3\" matches the number 3. You will see the use of plural categories\n * and explicit number rules throughout later parts of this documentation.\n *\n * # Configuring ngPluralize\n * You configure ngPluralize by providing 2 attributes: `count` and `when`.\n * You can also provide an optional attribute, `offset`.\n *\n * The value of the `count` attribute can be either a string or an {@link guide/expression\n * Angular expression}; these are evaluated on the current scope for its bound value.\n *\n * The `when` attribute specifies the mappings between plural categories and the actual\n * string to be displayed. The value of the attribute should be a JSON object so that Angular\n * can interpret it correctly.\n *\n * The following example shows how to configure ngPluralize:\n *\n * <pre>\n * <ng-pluralize count=\"personCount\"\n                 when=\"{'0': 'Nobody is viewing.',\n *                      'one': '1 person is viewing.',\n *                      'other': '{} people are viewing.'}\">\n * </ng-pluralize>\n *</pre>\n *\n * In the example, `\"0: Nobody is viewing.\"` is an explicit number rule. If you did not\n * specify this rule, 0 would be matched to the \"other\" category and \"0 people are viewing\"\n * would be shown instead of \"Nobody is viewing\". You can specify an explicit number rule for\n * other numbers, for example 12, so that instead of showing \"12 people are viewing\", you can\n * show \"a dozen people are viewing\".\n *\n * You can use a set of closed braces(`{}`) as a placeholder for the number that you want substituted\n * into pluralized strings. In the previous example, Angular will replace `{}` with\n * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder\n * for <span ng-non-bindable>{{numberExpression}}</span>.\n *\n * # Configuring ngPluralize with offset\n * The `offset` attribute allows further customization of pluralized text, which can result in\n * a better user experience. For example, instead of the message \"4 people are viewing this document\",\n * you might display \"John, Kate and 2 others are viewing this document\".\n * The offset attribute allows you to offset a number by any desired value.\n * Let's take a look at an example:\n *\n * <pre>\n * <ng-pluralize count=\"personCount\" offset=2\n *               when=\"{'0': 'Nobody is viewing.',\n *                      '1': '{{person1}} is viewing.',\n *                      '2': '{{person1}} and {{person2}} are viewing.',\n *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',\n *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}\">\n * </ng-pluralize>\n * </pre>\n *\n * Notice that we are still using two plural categories(one, other), but we added\n * three explicit number rules 0, 1 and 2.\n * When one person, perhaps John, views the document, \"John is viewing\" will be shown.\n * When three people view the document, no explicit number rule is found, so\n * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.\n * In this case, plural category 'one' is matched and \"John, Marry and one other person are viewing\"\n * is shown.\n *\n * Note that when you specify offsets, you must provide explicit number rules for\n * numbers from 0 up to and including the offset. If you use an offset of 3, for example,\n * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for\n * plural categories \"one\" and \"other\".\n *\n * @param {string|expression} count The variable to be bounded to.\n * @param {string} when The mapping between plural category to its corresponding strings.\n * @param {number=} offset Offset to deduct from the total number.\n *\n * @example\n    <doc:example>\n      <doc:source>\n        <script>\n

Each template\n * instance gets its own scope, where the given loop variable is set to the current collection item,\n * and `$index` is set to the item index or key.\n *\n * Special properties are exposed on the local scope of each template instance, including:\n *\n *   * `$index` – `{number}` – iterator offset of the repeated element (0..length-1)\n *   * `$first` – `{boolean}` – true if the repeated element is first in the iterator.\n *   * `$middle` – `{boolean}` – true if the repeated element is between the first and last in the iterator.\n *   * `$last` – `{boolean}` – true if the repeated element is last in the iterator.\n *\n * Additionally, you can also provide animations via the ngAnimate attribute to animate the **enter**,\n * **leave** and **move** effects.\n *\n * @animations\n * enter - when a new item is added to the list or when an item is revealed after a filter\n * leave - when an item is removed from the list or when an item is filtered out\n * move - when an adjacent item is filtered out causing a reorder or when the item contents are reordered\n *\n * @element ANY\n * @scope\n * @priority 1000\n * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These\n *   formats are currently supported:\n *\n *   * `variable in expression` – where variable is the user defined loop variable and `expression`\n *     is a scope expression giving the collection to enumerate.\n *\n *     For example: `track in cd.tracks`.\n *\n *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,\n *     and `expression` is the scope expression giving the collection to enumerate.\n *\n *     For example: `(name, age) in {'adam':10, 'amalie':12}`.\n *\n *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking function\n *     which can be used to associate the objects in the collection with the DOM elements. If no tractking function\n *     is specified the ng-repeat associates elements by identity in the collection. It is an error to have\n *     more then one tractking function to  resolve to the same key. (This would mean that two distinct objects are\n *     mapped to the same DOM element, which is not possible.)\n *\n *     For example: `item in items` is equivalent to `item in items track by $id(item)'. This implies that the DOM elements\n *     will be associated by item identity in the array.\n *\n *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique\n *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements\n *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM\n *     element in the same way ian the DOM.\n *\n *     For example: `item in items track by item.id` Is a typical pattern when the items come from the database. In this\n *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`\n *     property is same.\n *\n * @example\n * This example initializes the scope to a list of names and\n * then uses `ngRepeat` to display every person:\n  <example animations=\"true\">\n    <file name=\"index.html\">\n      <div ng-init=\"friends = [\n        {name:'John', age:25, gender:'boy'},\n        {name:'Jessie', age:30, gender:'girl'},\n        {name:'Johanna', age:28, gender:'girl'},\n        {name:'Joy', age:15, gender:'girl'},\n        {name:'Mary', age:28, gender:'girl'},\n        {name:'Peter', age:95, gender:'boy'},\n        {name:'Sebastian', age:50, gender:'boy'},\n        {name:'Erika', age:27, gender:'girl'},\n        {name:'Patrick', age:40, gender:'boy'},\n        {name:'Samantha', age:60, gender:'girl'}\n      ]\">\n        I have {{friends.length}} friends.

and **leave** effects.\n *\n * @animations\n * enter - happens just after the ngView contents are changed (when the new view DOM element is inserted into the DOM)\n * leave - happens just after the

You can also find this file on Google CDN, bower as well as at\n * {@link http://code.angularjs.org/ code.angularjs.org}.\n *\n * Finally load the module in your application:\n *\n *        angular.module('app', ['ngResource']);\n *\n * and you are ready to get started!\n *\n * @param {string} url A parametrized URL template with parameters prefixed by `:` as in\n *   `/user/:username`. If you are using a URL with a port number (e.g.\n *   `http://example.com:8080/api`), you'll need to escape the colon character before the port\n *   number, like this: `$resource('http://example.com\\\\:8080/api')`.\n *\n *   If you are using a url with a suffix, just add the suffix, like this:\n *   `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')\n *   or even `$resource('http://example.com/resource/:resource_id.:format')`\n *   If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be\n *   collapsed down to a single `.`.  If you need this sequence to appear and not collapse then you\n *   can escape it with `/\\.`.\n *\n * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in\n *   `actions` methods. If any of the parameter value is a function, it will be executed every time\n *   when a param value needs to be obtained for a request (unless the param was overridden).\n *\n *   Each key value in the parameter object is first bound to url template if present and then any\n *   excess keys are appended to the url search query after the `?`.\n *\n *   Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in\n *   URL `/path/greet?salutation=Hello`.\n *\n *   If the parameter value is prefixed with `@` then the value of that parameter is extracted from\n *   the data object (useful for non-GET operations).\n *\n * @param {Object.<Object>=} actions Hash with declaration of custom action that should extend the\n *   default set of resource actions. The declaration should be created in the format of {@link\n *   ng.$http#Parameters $http.config}:\n *\n *       {action1: {method:?, params:?, isArray:?, headers:?, ...},\n *        action2: {method:?, params:?, isArray:?, headers:?, ...},\n *        ...}\n *\n *   Where:\n *\n *   - **`action`** – {string} – The name of action. This name becomes the name of the method on your\n *     resource object.\n *   - **`method`** – {string} – HTTP request method. Valid methods are: `GET`, `POST`, `PUT`, `DELETE`,\n *     and `JSONP`.\n *   - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of the\n *     parameter value is a function, it will be executed every time when a param value needs to be\n *     obtained for a request (unless the param was overridden).\n *   - **`url`** – {string} – action specific `url` override. The url templating is supported just like\n *     for the resource-level urls.\n *   - **`isArray`** – {boolean=} – If true then the returned object for this action is an array, see\n *     `returns` section.\n *   - **`transformRequest`** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –\n *     transform function or an array of such functions. The transform function takes the http\n *     request body and headers and returns its transformed (typically serialized) version.\n *   - **`transformResponse`** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –\n *     transform function or an array of such functions. The transform function takes the http\n *     response body and headers and returns its transformed (typically deserialized) version.\n *   - **`cache`** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the\n *     GET request, otherwise if a cache instance built with\n *     {@link ng.$cacheFactory $cacheFactory}, this cache will be used for\n *     caching.\n *   - **`timeout`** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} that\n *     should abort the request when resolved.\n *   - **`withCredentials`** - `{boolean}` - whether to to set the `withCredentials` flag on the\n *     XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5\n *     requests with credentials} for more information.\n *   - **`responseType`** - `{string}` - see {@link\n *     https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType requestType}.\n *\n * @returns {Object} A resource \"class\" object with methods for the default set of resource actions\n *   optionally extended with custom `actions`. The default set contains these actions:\n *\n *       { 'get':    {method:'GET'},\n *         'save':   {method:'POST'},\n *         'query':  {method:'GET', isArray:true},\n *         'remove': {method:'DELETE'},\n *         'delete': {method:'DELETE'} };\n *\n *   Calling these methods invoke an {@link ng.$http} with the specified http method,\n *   destination and parameters. When the data is returned from the server then the object is an\n *   instance of the resource class. The actions `save`, `remove` and `delete` are available on it\n *   as  methods with the `$` prefix. This allows you to easily perform CRUD operations (create,\n *   read, update, delete) on server-side data like this:\n *   <pre>\n        var User = $resource('/user/:userId', {userId:'@id'});\n        var user = User.get({userId:123}, function() {\n          user.abc = true;\n          user.$save();\n        });\n     </pre>\n *\n *   It is important to realize that invoking a $resource object method immediately returns an\n *   empty reference (object or array depending on `isArray`). Once the data is returned from the\n *   server the existing reference is populated with the actual data. This is a useful trick since\n *   usually the resource is assigned to a model which is then rendered by the view. Having an empty\n *   object results in no rendering, once the data arrives from the server then the object is\n *   populated with the data and the view automatically re-renders itself showing the new data. This\n *   means that in most case one never has to write a callback function for the action methods.\n *\n *   The action methods on the class object or instance object can be invoked with the following\n *   parameters:\n *\n *   - HTTP GET \"class\" actions: `Resource.action([parameters], [success], [error])`\n *   - non-GET \"class\" actions: `Resource.action([parameters], postData, [success], [error])`\n *   - non-GET instance actions:  `instance.$action([parameters], [success], [error])`\n *\n *\n *   The Resource instances and collection have these additional properties:\n *\n *   - `$then`: the `then` method of a {@link ng.$q promise} derived from the underlying\n *     {@link ng.$http $http} call.\n *\n *     The success callback for the `$then` method will be resolved if the underlying `$http` requests\n *     succeeds.\n *\n *     The success callback is called with a single object which is the {@link ng.$http http response}\n *     object extended with a new property `resource`. This `resource` property is a reference to the\n *     result of the resource action — resource object or array of resources.\n *\n *     The error callback is called with the {@link ng.$http http response} object when an http\n *     error occurs.\n *\n *   - `$resolved`: true if the promise has been resolved (either with success or rejection);\n *     Knowing if the Resource has been resolved is useful in data-binding.\n *\n * @example\n *\n * # Credit card resource\n *\n * <pre>\n     // Define CreditCard class\n     var CreditCard = $resource('/user/:userId/card/:cardId',\n      {userId:123, cardId:'@id'}, {\n       charge: {method:'POST', params:{charge:true}}\n      });\n\n     // We can retrieve a collection from the server\n     var cards = CreditCard.query(function() {\n       // GET: /user/123/card\n       // server returns: [ {id:456, number:'1234', name:'Smith'} ];\n\n       var card = cards[0];\n       // each item is an instance of CreditCard\n       expect(card instanceof CreditCard).toEqual(true);\n       card.name = \"J. Smith\";\n       // non GET methods are mapped onto the instances\n       card.$save();\n       // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}\n       // server returns: {id:456, number:'1234', name: 'J. Smith'};\n\n       // our custom method is mapped as well.\n       card.$charge({amount:9.99});\n       // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}\n     });\n\n     // we can create an instance as well\n     var newCard = new CreditCard({number:'0123'});\n     newCard.name = \"Mike Smith\";\n     newCard.$save();\n     // POST: /user/123/card {number:'0123', name:'Mike Smith'}\n     // server returns: {id:789, number:'01234', name: 'Mike Smith'};\n     expect(newCard.id).toEqual(789);\n * </pre>\n *\n * The object returned from this function execution is a resource \"class\" which has \"static\" method\n * for each action in the definition.\n *\n * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and `headers`.\n * When the data is returned from the server then the object is an instance of the resource type and\n * all of the non-GET methods are available with `$` prefix.
