In that case, I think it's faster if you generate them when you need them rather
than incrementally update them. I generate them on the fly, and so does Dr.
Hyatt. We use different methods though. He uses rotated bitboards and I generate
them with a few bitwise operations to avoid table lookups altogether. I don't
like rotated bitboards very much :)
