title: How to use the Timeline in tweenjs
body: <p>Docu says:</p>
  
  <blockquote>
    <p>Timeline The Timeline class synchronizes multiple tweens and allows
    them to be controlled as a group.</p>
  </blockquote>
  
  <p>but there is no example how to use it. If I create a Timeline with </p>
  
  <pre><code>var tl = createjs.Timeline();
  </code></pre>
  
  <p>none of the shapes are rendered anymore.</p>
  
  <p>Timeline is a great feature in TweenMax and I like to use it in the canvas too. </p>
