/**
* 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

one

two

three

* @result [

two

]
*
* @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.
