/**
* @ngdoc function
* @name angular.element
* @function
*
* @description
* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
* `angular.element` can be either an alias for [jQuery](http://api.jquery.com/jQuery/) function, if
* jQuery is available, or a function that wraps the element or string in Angular's jQuery lite
* implementation (commonly referred to as jqLite).
*
* Real jQuery always takes precedence over jqLite, provided it was loaded before `DOMContentLoaded`
* event fired.
*
* jqLite is a tiny, API-compatible subset of jQuery that allows
* Angular to manipulate the DOM. jqLite implements only the most commonly needed functionality
* within a very small footprint, so only a subset of the jQuery API - methods, arguments and
* invocation styles - are supported.
*
* Note: All element references in Angular are always wrapped with jQuery or jqLite; they are never
* raw DOM references.
*
* ## Angular's jqLite
* Angular's lite version of jQuery provides only the following jQuery methods:
*
* - [addClass()](http://api.jquery.com/addClass/)
* - [after()](http://api.jquery.com/after/)
* - [append()](http://api.jquery.com/append/)
* - [attr()](http://api.jquery.com/attr/)
* - [bind()](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
* - [children()](http://api.jquery.com/children/) - Does not support selectors
* - [clone()](http://api.jquery.com/clone/)
* - [contents()](http://api.jquery.com/contents/)
* - [css()](http://api.jquery.com/css/)
* - [data()](http://api.jquery.com/data/)
* - [eq()](http://api.jquery.com/eq/)
* - [find()](http://api.jquery.com/find/) - Limited to lookups by tag name
* - [hasClass()](http://api.jquery.com/hasClass/)
* - [html()](http://api.jquery.com/html/)
* - [next()](http://api.jquery.com/next/) - Does not support selectors
* - [on()](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
* - [off()](http://api.jquery.com/off/) - Does not support namespaces or selectors
* - [parent()](http://api.jquery.com/parent/) - Does not support selectors
* - [prepend()](http://api.jquery.com/prepend/)
* - [prop()](http://api.jquery.com/prop/)
* - [ready()](http://api.jquery.com/ready/)
* - [remove()](http://api.jquery.com/remove/)
* - [removeAttr()](http://api.jquery.com/removeAttr/)
* - [removeClass()](http://api.jquery.com/removeClass/)
* - [removeData()](http://api.jquery.com/removeData/)
* - [replaceWith()](http://api.jquery.com/replaceWith/)
* - [text()](http://api.jquery.com/text/)
* - [toggleClass()](http://api.jquery.com/toggleClass/)
* - [triggerHandler()](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.
* - [unbind()](http://api.jquery.com/off/) - Does not support namespaces
* - [val()](http://api.jquery.com/val/)
* - [wrap()](http://api.jquery.com/wrap/)
*
* ## jQuery/jqLite Extras
* Angular also provides the following additional methods and events to both jQuery and jqLite:
*
* ### Events
* - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
* on all DOM nodes being removed. This can be used to clean up and 3rd party bindings to the DOM
* element before it is removed.
* ### Methods
* - `controller(name)` - retrieves the controller of the current element or its parent. By default
* retrieves controller associated with the `ngController` directive. If `name` is provided as
* camelCase directive name, then the controller for this directive will be retrieved (e.g.
* `'ngModel'`).
* - `injector()` - retrieves the injector of the current element or its parent.
* - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current
* element or its parent.
* - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
* parent element is reached.
*
* @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
* @returns {Object} jQuery object.
