<!-- HoverIntent -->
 +
<script type="text/javascript">

/**
 +
* hoverIntent is similar to jQuery's built-in "hover" method except that
 +
* instead of firing the handlerIn function immediately, hoverIntent checks
 +
* to see if the user's mouse has slowed down (beneath the sensitivity
 +
* threshold) before firing the event. The handlerOut function is only
 +
* called after a matching handlerIn.
 +
*
 +
* hoverIntent r7 // 2013.03.11 // jQuery 1.9.1+
 +
* http://cherne.net/brian/resources/jquery.hoverIntent.html
 +
*
 +
* You may use hoverIntent under the terms of the MIT license. Basically that
 +
* means you are free to use hoverIntent as long as this header is left intact.
