Ok, for this example you can just start it with:

TreeDemo new openWithSpec

It opens a window with two panes, the upper pane shows a tree with some
nodes (subclasses of class Morph)
The lower pane shows the text(name) of the selected node. You can change
and accept (cmd+s) the text in the
lower pane, which will update the name of the tree node.
