Associate given node with it's own name.
<p>If not NodeFinished, then we understand that we're parsing / saving the node's contents now. If NodeFinished, then we know the node contents are fully parsed / saved now. This information helps us to detect cycles in VRML/X3D DEF/USE graph. For now, we just disallow such cycles. Still, we allow ROUTEs from inside the node, so calling with NodeFinished = false is still useful for parsing.</p>

Check is Node bound in the current namespace. <code>False</code> means that node is not within this namespace, possibly it's name was hidden by other node with the same name.
<p>Doesn't check is Node bound to it's name (Node.NodeName) or something else. So this assumes that node can only be bound (if at all) only to it's own name, which is true during parsing (when nothing can change in the middle of parsing).</p>

If <code>True</code> (determined at construction time), then destroyed nodes will be automatically removed from this list. This allows you to safely destroy node instances during this objects lifetime, without worrying that some dangling pointers remain on this list.
