title: How to implement two finger tap using hammer.js
body: <p>I am trying to implement two finger tap using hammer.js on iOS Safari but don't have any success. As I understand if both the finger touches in span of little difference even 50ms it triggers pinch gesture.</p>
  
  <p>With tap event I am checking <code>event.gesture.touches.length === 2</code> it satisfy my requirement but its efficiency is very low.</p>
  
  <p>Can you please help me to achieve this?</p>
