Class Overview
This is the implementation class for the FlattenedTreeNode
interface. In general, this class delegates to a held GenericTreeNode with the exception of the "parent" link. When a root
node is being traversed, it may not be the root node in its containing
graph. Instead of requiring the node to be a root in the larger tree, we
simply manage the parent link in this object.

Public Methods
public int getChildCount ()
