title: Doctrine 2 nested set - retrieve full tree in single query
body: <p>I'm using <a href="https://github.com/stof/StofDoctrineExtensionsBundle" rel="noreferrer">stof/StofDoctrineExtensionsBundle</a> (Bundle wrapper for <a href="https://github.com/Atlantic18/DoctrineExtensions" rel="noreferrer">Atlantic18/DoctrineExtensions</a>) to implement a Nested Set (tree) entity. The entity is configured and working, but I can't figure out how to retrieve all root notes with all of their children (full trees) in a single query. I currently have the full collection returning however it lazy loads all children, meaning a large number of queries is performed.</p>
  
  <p>Thanks for any help.</p>
