Commit my work so far on a generator for Nikoli's `Block Puzzle'. It

works, but it's slow, and the puzzles are currently at a relatively
low level of difficulty. Also this is a generator only: no UI yet
(because I'm waiting to see if I can make the generator practical
before bothering to write the rest).
