Wumpus.Tree.Design

A variant of the tree drawing algorithm from Andrew Kennedy - Functional Pearls Drawing Trees 1996.

Acknowledgment - although based on Andrew Kennedy's algorithm, this version uses absolute extents rather than relative ones and is a somewhat different in detail if not in spirit to the original.

Any mistakes are mine of course.
