/**
* 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.
