title: can't get ScrollMagic parralax tween to work
body: <p>I'm trying to implement the code from the first example here: </p>
  
  <p><a href="http://janpaepke.github.io/ScrollMagic/examples/advanced/parallax_scrolling.html" rel="nofollow">http://janpaepke.github.io/ScrollMagic/examples/advanced/parallax_scrolling.html</a></p>
  
  <p>The following tween works (but tweens immediately)...</p>
  
  <pre><code>var tween = new TimelineMax().add([
          TweenMax.to('#test',1,{top:"50%",ease:Linear.easeNone})
      ]);
  </code></pre>
  
  <p>When I add the following code...</p>
  
  <pre><code>var scene = new ScrollMagic.Scene({
      triggerElement:'#test' ,
      duration:500
  })
      .setTween(tween)
      .addTo(controller);
  </code></pre>
  
  <p>I get the below error:</p>
  
  <p><code>Uncaught TypeError: (intermediate value).setTween is not a function</code></p>
  
  <p>I'm going crazy trying to figure this out. What am I doing wrong?</p>
