// Game review consists of the board, some information about the players, the game tree, and any
// commentary on the current move. This requires four major components, some of which are easier
// than others. The game board has to be kept in sync with the game tree, so there's a
// communication channel there.
//
// I'll get all of the information about the game from the core, and then render everything in the
// UI. So this will be a heavy lift on the UI side.
