-/* 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.
- *
- * // basic usage ... just like .hover()
- * .hoverIntent( handlerIn, handlerOut )
- * .hoverIntent( handlerInOut )
- *
- * // basic usage ... with event delegation!
- * .hoverIntent( handlerIn, handlerOut, selector )
- * .hoverIntent( handlerInOut, selector )
- *
- * // using a basic configuration object
- * .hoverIntent( config )
- *
- * @param  handlerIn   function OR configuration object
- * @param  handlerOut  function OR selector for delegation OR undefined
- * @param  selector    selector OR undefined
