title: Detect the horizontal mousewheel
body: <p>I would like to make a differenciation between three cases : </p>
  
  <pre><code>e.preventDefault();
  if(Mousewheel.direction = Left)
      base.goForward();
  else if(Mousewheel.direction = Right)
      base.goBack();
  else{   
      //Doing normal slide                            
  </code></pre>
  
  <p>But I can't find anything indicating if the mousewheel is horizontal or vertical, the only returns of the plugin Mousewheel, being delta and event. </p>
  
  <p>If someone knows how i could make a differenciation between horizontal and vertical wheeling, thanks for sharing your tips.</p>
