Is that meaningful? I want it to have state. The state is currently undefined, but it's gonna be some String. I think currently that'll be a comma-separated list like:

wR,wN,wB,wQ,wK,wB,wN,wR,
wP,wP,wP,wP,wP,wP,wP,wP,
,,,,,,,,
,,,,,,,,
,,,,,,,,
,,,,,,,,
bP,bP,bP,bP,bP,bP,bP,bP,
bR,bN,bB,bQ,bK,bB,bN,bR,

I went with FEN format instead.
