"""
This is the web server that interacts with the tic tac toe engine.
Because it is loosely coupled, if we wanted to swap out
we would just need to implement a .move() that takes a list
and returns a dict with keys board, game_over, and winner
where board is a 3-list of 3-lists, game_over is a bool and
winner is 'X','O', or None
