title: How to add a new node to a dijit.Tree
body: <p>I want to add a new node to a dijit.ree as a sibling of the currently selected node.  I've found sample code (I'm new to dojo) that adds a new item to the tree using the newItem method of ItemFileWriteStore, but the new item always appears at the bottom of the tree.  How would I add to the store at a specified position, in particular the position corresponding to the current selection?  Pointers to sample code would be welcome :)</p>
  
  <p>Thanks,
  Larry</p>
