/*
* Improved jQuery.cookie plugin – http://mths.be/cookie
* 
* Based on
*  - the original MIT/GPL-licensed jQuery cookie plugin by Klaus Hartl (stilbuero.de)
*  - readCookie() by Lea Verou, James Padolsey and Juriy Zaytsev: http://mths.be/abe
*
* This plugin intentionally uses the same syntax as the original jQuery cookie plugin, for backwards compatibility.
*
* Examples:
* =========
*
* Create a cookie with the given name and value and other optional parameters.
*
* @example $.cookie('the_cookie', 'the_value');
* @desc Set the value of a cookie.
* @example $.cookie('the_cookie', 'the_value', { expires: 7, path: '/', domain: 'jquery.com', secure: true });
* @desc Create a cookie with all available options.
* @example $.cookie('the_cookie', 'the_value');
* @desc Create a session cookie.
* @example $.cookie('the_cookie', null);
* @desc Delete a cookie by passing null as value. Keep in mind that you have to use the same path and domain used when the cookie was set.
*
* @param String name The name of the cookie.
* @param String value The value of the cookie.
* @param Object options An object literal containing key/value pairs to provide optional cookie attributes.
* @option Number|Date expires Either an integer specifying the expiration date from now on in days or a Date object.
*                             If a negative value is specified (e.g. a date in the past), the cookie will be deleted.
*                             If set to null or omitted, the cookie will be a session cookie and will not be retained when the the browser exits.
* @option String path The value of the path atribute of the cookie (default: path of page that created the cookie).
* @option String domain The value of the domain attribute of the cookie (default: domain of page that created the cookie).
* @option Boolean secure If true, the secure attribute of the cookie will be set and the cookie transmission will require a secure protocol (like HTTPS).
* @type undefined
*
* Get the value of a cookie with the given name.
*
* @example $.cookie('the_cookie');
* @desc Get the value of a cookie.
*
* @param String name The name of the cookie.
* @return The value of the cookie.
* @type String
