TSUNAGI_SIZESconstant

TSUNAGI'S LEVELS, COUNTED: which sizes there are, how many levels each has, and which of them a player has opened. The levels themselves are data, each size its own import (@johnmorrisdotca/tsunagi/levels-7, or every size through @johnmorrisdotca/tsunagi/levels), so nothing here carries a board.

A level is not made from a seed: level 12 at 7×7 is one board for every player on every day, so a time on it can be compared with anybody's.
