/**
 * hoverIntent is similar to jQuery's built-in "hover" function except that
 * instead of firing the onMouseOver event immediately, hoverIntent checks
 * to see if the user's mouse has slowed down (beneath the sensitivity
 * threshold) before firing the onMouseOver event.
 * 
 * hoverIntent r6 // 2011.02.26 // jQuery 1.5.1+
 * <http://cherne.net/brian/resources/jquery.hoverIntent.html>
 * 
 * hoverIntent is currently available for use in all personal or commercial 
 * projects under both MIT and GPL licenses. This means that you can choose 
 * the license that best suits your project, and use it accordingly.
 * 
 * // basic usage (just like .hover) receives onMouseOver and onMouseOut functions
 * $("ul li").hoverIntent( showNav , hideNav );
 * 
 * // advanced usage receives configuration object only
 * $("ul li").hoverIntent({
 *	sensitivity: 7, // number = sensitivity threshold (must be 1 or higher)
 *	interval: 100,   // number = milliseconds of polling interval
 *	over: showNav,  // function = onMouseOver callback (required)
 *	timeout: 0,   // number = milliseconds delay before onMouseOut function call
 *	out: hideNav    // function = onMouseOut callback (required)
 * });
 * 
 * @param  f  onMouseOver function || An object with configuration options
 * @param  g  onMouseOut function  || Nothing (use configuration options object)
