title: How to swipeleft and swiperight
body: <p>Apologies in advance - this is such a fundamental question:
  Why are swipeleft and swiperight not working? </p>
  
  <pre><code>(function() {
      $('img').on('swiperight', swipeRight);
      function swipeRight(myEvent){ 
          myEvent.stopPropagation();
          alert('swipeRight');
      };
  
      $('img').on('swipeleft', swipeLeft);
      function swipeLeft(myEvent) { 
          myEvent.stopPropagation();
          alert('swipeLeft');
      };
  })();
  </code></pre>
  
  <p>I've loaded jQuery, but do I need to load a entire library like jQuery Mobile or Angular?
  I just want to slide from 1 picture to the next.</p>
