I think that I can post too quickly sometimes. I'm actually thinking
of disjoint sets rather than union sets. It's really a way to track
chain identifiers for stones via incremental O(1) updates. Now I'm
curious what you guys are really talking about. What's a union-find?

I guess my question about pseudo-liberties stands. As far as I know, I
made up the term, but it's very possible I'm not the only one.
