TREELAYOUT

 

 Lay out a tree or forest.

  [x,y,h,s] = treelayout(parent,post)

      parent is the vector of parent pointers, with 0 for a root.

      post is a postorder permutation on the the tree nodes.

      (If post is omitted we compute it here.)

      x and y are vectors of coordinates in the unit square at which 

      to lay out the nodes of the tree to make a nice picture.

      Optionally, h is the height of the tree and s is the 

      number of vertices in the top-level separator.
