<P>
If there is any reason for your node to access its objref (eg to find
out its GraphID, for example), then you can add the objref to its edge
list (say the first item on the edgelist by convention). Then you can
refer to things like <code>begin()->ID</code>, <code>begin()->proc</code> etc.
<P>
The <code>Graph::Prepare_Neighbours()</code> and
<code>Graph::Partition_Objects()</code> methods ignore self-linking edges.
