Expand up

[tnike1]

I've added a little method to the MooTreeNode class that you might
find usefull.
Its goal is to make a particular node visible by opening all its
parents.

If you need to preselect a node, you then do :
selectednode.expandup(); tree.select(selectednode);

To have it visible and selected.

Have fun!
