<DD>Node destructor. Note, is protected so that Nodes cannot
be deleted other than by being dereferenced and the reference
count being zero (see osg::Referenced), preventing the deletion
of nodes which are still in use. This also means that
Node's cannot be created on stack i.e Node node will not compile,
forcing all nodes to be created on the heap i.e Node* node
= new Node().
