/* 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
