title: Load static data to Ext.data.TreeStore
body: <p>Can I load some static data to <code>Ext.data.TreeStore</code> instance?
  It is pretty straightforward for Ext.data.Store - all we have to do - is to add <a href="http://docs.sencha.com/ext-js/4-0/#!/api/Ext.data.Store-cfg-data" rel="nofollow">data param</a> to config. </p>
  
  <p>But I can not see such thing for <a href="http://docs.sencha.com/ext-js/4-0/#!/api/Ext.data.TreeStore" rel="nofollow">Ext.data.TreeStore</a>.</p>
