CPL Update

I'm also working on finding a New Flavors equivalent that works
within the topological sort framework. I have one such equivalent,
which can be explained in either of two ways.  I think I have a second
algorithm that produces the same results as the New Flavors algorithm
which can be described differently from the topological sort algorithms
and the New Flavors algorithm - it is of the form of a certain weird
treewalk and doesn't do multiple depth-first walks.

I'll send out the details once I consult with my algorithms wizard,
which should be tomorrow afternoon.
