How to use the Timeline in tweenjs
<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>
