/**
* This function accepts a string containing a CSS selector,
* basic XPath, or raw HTML, which is then used to match a set of elements.
* The HTML string is different from the traditional selectors in that
* it creates the DOM elements representing that HTML string, on the fly,
* to be (assumedly) inserted into the document later.
*
* 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 and remembers them for later use.
*
* 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 $("<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.
*
* @name $
* @param String expr An expression to search with, or a string of HTML to create on the fly.
