Detailed Description

Identifier for board state including history.

This class can be used, for instance, to uniquely remember a board position for reusing parts of previous computations. The state includes:

• the board size
• the rules
• the setup stones and color to play before any moves were played
• the history of moves (needed if super-ko rules are used)
• the current color to play
