-/**
-* 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 r5 // 2007.03.27 // jQuery 1.1.2+
-* <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)
