# Models work like this; feel free to inherit from BaseModel to get the
# necessary helpful things.
#
# Instance variables of models represent unknowns or random data. The important
# calls are
# * player_sees_player_and_claims
# * votes
# * mission
# And that's it! Delegate to other functions as necessary (see the example
# role-based map below) These functions should return one of the following,
# depending on the circumstance:
# * True -- This set of statements could totally happen (or randomness chose
# that it did)
#
# * False -- This set of statements could happen, but is unlikely (or
# randomness chose that it didn't)
#
# * None -- This set of statements could NEVER happen, please remove them from
# consideration.
