Require files using RequireJS before running Jasmine specs

* jasmine.requirejs() returns a function that will load the file(s) required
* and will wait until it's done before proceeding with running specs.
* The function returned is intended to be passed to beforeEach() so the file(s)
* is(are) loaded before running each spec.
*
* Syntax:
*
* jasmine.requirejs([options,] files, [callback])
* alias: _requires([options,] files, [callback])
*
* Where:
* - options is a configuration object like the one you
* can bass to RequireJS require() function (i.e.: baseUrl, paths, etc...)
* and
* - files is an array of files to require (i.e.: ['lib/common', 'views/main'])
* - callback is the named parameters as you get from requirejs (ie function(common, main){})
*
* Examples:
* 
* Loading either using jasmine.requirejs or via alias _requires
*
* beforeEach(jasmine.requirejs({
*     baseUrl: '/public/javascripts'
*   }, 
*   ['lib/app.help-mgr']
*  ));
*
* or
*
* beforeEach(_requires(['lib/app.help-mgr']));
*
*
* Loading using alias _requires and getting access to the return functions
*
*  (using the arguments passed through)
* beforeEach(_requires(['underscore'], function(){ _ = arguments[0]}));
*
*   or 
*
*  (using explicit arguments and then scoping more widely for the tests)
* beforeEach(_requires(['underscore'], function( u ){ _ = u }));
*
*
* Additional Option 1: you can set the require config for multiple requires
*
* jasmine.requirejs.config = {
*    BaseUrl: '/public/javascripts'
*   } 
*
