- /**
- * 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)
