-- current castle tests are wrong,
- UCI move: for castling is kingpos, rookpos.
- test all possible chess960 and classical positions.
- - castling code can be simplified and end position for castling is the same
- as classical.
- rename fen.c to be more unique so it can be installed in $PATH.
- more tests.
- test more long sequence and halfmove and movenumber counts.
