Lay out tree or forest
[x,y] = treelayout(parent,post)
lays out a tree or a forest.
parent is the vector of parent pointers, with
0 for a root.
post is an optional postorder permutation on the tree nodes. If you omit
treelayout computes it.
y are vectors of coordinates in the unit square at which to lay out the nodes of the tree to make a nice picture.
[x,y,h,s] = treelayout(parent,post)
also returns the height of the tree h and the number of vertices
s in the top-level separator.
