/**
 * This function accepts a string containing a CSS or
 * basic XPath selector which is then used to match a set of elements.
 *
 * The core functionality of jQuery centers around this function.
 * Everything in jQuery is based upon this, or uses this in some way.
 * The most basic use of this function is to pass in an expression
 * (usually consisting of CSS or XPath), which then finds all matching
 * elements.
 *
 * By default, if no context is specified, $() looks for DOM elements within the context of the
 * current HTML document. If you do specify a context, such as a DOM
 * element or jQuery object, the expression will be matched against
 * the contents of that context.
 *
 * See [[DOM/Traversing/Selectors]] for the allowed CSS/XPath syntax for expressions.
 *
 * @example $("div > p")
 * @desc Finds all p elements that are children of a div element.
 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
 * @result [ <p>two</p> ]
 *
 * @example $("input:radio", document.forms[0])
 * @desc Searches for all inputs of type radio within the first form in the document
 *
 * @example $("div", xml.responseXML)
 * @desc This finds all div elements within the specified XML document.
 *
 * @name $
 * @param String expr An expression to search with
 * @param Element|jQuery context (optional) A DOM Element, Document or jQuery to use as context
 * @cat Core
 * @type jQuery
 * @see $(Element)
 * @see $(Element<Array>)

 * and appends it to the body element. Internally, an
 * element is created and its innerHTML property set to the given markup.
 * It is therefore both quite flexible and limited.

 * operated on. While this function is, technically, chainable - there really
 * isn't much use for chaining against it.
 *
 * You can have as many $(document).ready events on your page as you like.
 *
 * See ready(Function) for details about the ready event. 
 * 
 * @example $(function(){
 *   // Document is ready
 * });
 * @desc Executes the function when the DOM is ready to be used.
 *
 * @example jQuery(function($) {
 *   // Your code using failsafe $ alias here...
