+/**
+* 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)
+* @author    Brian Cherne <brian@cherne.net>
