-"""      turtle-example-suite:
-
-             tdemo_tree.py
-
-Displays a 'breadth-first-tree' - in contrast
-to the classical Logo tree drawing programs,
-which use a depth-first-algorithm.
-
-Uses:
-(1) a tree-generator, where the drawing is
-quasi the side-effect, whereas the generator
-always yields None.
-(2) Turtle-cloning: At each branching point the
-current pen is cloned. So in the end there
-are 1024 turtles.
