code: function stopDetect() {
      // clone current data to the store as the previous gesture
      // used for the double tap gesture, since this is an other gesture detect session
      this.previous = Hammer.utils.extend({}, this.current);
  
      // reset the current
      this.current = null;
  
      // stopped!
      this.stopped = true;
    }
docs: clear the Hammer.gesture vars
  this is called on endDetect, but can also be used when a final Hammer.gesture has been detected
  to stop other Hammer.gestures from being fired
