/**
 * 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, $() looks for DOM elements within the context of the
 * current HTML document.
 *
 * @example $("div > p")
 * @desc This 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 context (optional) A DOM Element, or Document, representing the base context.

/**
 * This function accepts a string of raw HTML.
 *
 * The HTML string is different from the traditional selectors in that

 *
 * @example $("<div><p>Hello</p></div>").appendTo("#body")
 * @desc Creates a div element (and all of its contents) dynamically, 
 * and appends it to the element with the ID of body. Internally, an
 * element is created and it's innerHTML property set to the given markup.
 * It is therefore both quite flexible and limited.
