Remaining Tasks

Write play_game function (recording numbers of pieces captured and total number of moves, and making it possible to choose utility functions from the terminal)
store number of rows and number of cols in a separate object, rather than in each state, and rework code to work with that structure
play out multiple games between conquerer and evasive
name new utility functions
make sure new functions can beat evasive and conquerer at least 80% of the time
write instructions in readme
describe functions in report (particularly champion function)
