Partition Refinement Snapshot

I've just passed the thousand line mark on the partition backtrack code I'm writing this summer (thanks to the support of Google!), so I thought I'd take a snapshot of the work done so far and post it. As you can see, I've taken care of the datastructures, supporting functions, memory management, and I'm through the main loop itself. The naming conventions are better, the code is much more self-explanatory, and the loop is structured in a logical way, instead of a mazelike circuit of GOTOs. You can continue to watch my progress through the guts of NICE here, as I am trying to keep it current with what I am doing.
