title: Treeview in angular ui-grid
body: <p>I am trying to get a tree view working in angular ui-grid.  However I always get the error that the template for the treeViewRowHeader cannot be found.</p>
  
  <p>In the example there is no such template and no call is made to the server for this template.</p>
  
  <p>Anyone know where/how i should specify this template?</p>
  
  <p>BTW: Using RC21</p>
