title: How do I put a dynamic number of nodes in a Famo.us Engine scene graph?
body: <p>I'm trying to add an arbitrary number of nodes onto a FamousEngine Scene Graph. And I need the number of child nodes to be mutable as elements are added and removed. Think lazy loading list... </p>
  
  <p>In the old paradigm, any object with a render function could be tacked onto the "render tree" as long as it returned an array of "renderables". That returned array could change in length and composition frame to frame and the Engine would update the DOM accordingly. </p>
  
  <p>But the new Famo.us "Mixed Mode" FamousEngine has changed a lot. How do I do this now? </p>
