Also provide a way to take notes for physical game? Possibly entirely separate
code? Hopefully not...

Model:

Game:
 * # of players
 * Card orders?
 * # of clues left?

Player names?

Turn:
 * Visible cards at turn

Players intention to advance and bonus letter guesses?

Clue proposals:
 * Player # giving clue.
 * Turn # (to know what cards are visible)
 * List of indexes into visible cards
    * Should this just be a string like "423*"? Slightly complicated by bonus
        letters... but using A-Za-z for bonus letters and not allowing more
        than 52 bonus letter should be fine: the deck is only 64 cards anyway.

Votes on clue proposals? Separate table? Or part of a clue proposal?

Clues:
 * Clue proposal actuall used.

Player notes?
