+     * @function
+     *
+     * @description
+     * Wraps a raw DOM element or HTML string as [jQuery](http://jquery.com) element.
+     * `angular.element` is either an alias for [jQuery](http://api.jquery.com/jQuery/) function if
+     * jQuery is loaded or a function that wraps the element or string in angular's jQuery lite
+     * implementation.
+     *
+     * Real jQuery always takes precedence if it was loaded before angular.
+     *
+     * Angular's jQuery lite implementation is a tiny API-compatible subset of jQuery which allows
+     * angular to manipulate DOM.  The functions implemented are usually just the basic versions of
+     * them and might not support arguments and invocation styles.
+     *
+     * NOTE: All element references in angular are always wrapped with jQuery (lite) and are never
+     * raw DOM references.
+     *
+     * Angular's jQuery lite implements these functions:
+     *
+     * - [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/bind/)
+     * - [children()](http://api.jquery.com/children/)
+     * - [clone()](http://api.jquery.com/clone/)
+     * - [css()](http://api.jquery.com/css/)
+     * - [data()](http://api.jquery.com/data/)
+     * - [hasClass()](http://api.jquery.com/hasClass/)
+     * - [parent()](http://api.jquery.com/parent/)
+     * - [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/)
+     * - [trigger()](http://api.jquery.com/trigger/)
+     *
+     * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
+     * @returns {Object} jQuery object.
