title: Root Query Create and Delete in Relay.js
body: <p>I am trying to figure out how to create and delete nodes with Relay where I don't have a parent node. It seems that <code>NODE_DELETE</code>/<code>RANGE_DELETE</code> and <code>RANGE_ADD</code> all require a parent node. Is there a way to perform create and delete mutations from the root query object in Relay.js?</p>
  
  <p><strong><em>Note:</em></strong> I did find example where creates can be performed with a FIELDS_CHANGE query, but they lack any documentation or reason.</p>
