title: RESTful way to load an extJS tree
body: <p>For loading a tree(full load, not lazy-load on expand), I need to make a request to a REST resource on the server. The issue is that the tree is hierarchical and in the REST philosophy I can only request one resource at a time.</p>
  
  <p>How can I load the whole tree by following REST principles?</p>
  
  <p>Thanks.</p>
