"""
If we were to set up a Tic-Tac-Toe game, we would want to know whether the board's current state is solved, wouldn't we?
Our goal is to create a function that will check that for us!
Assume that the board comes in the form of a 3x3 array, where the value is 0 if a spot is empty, 1 if it is an "X", or 2 if it is an "O", like so:
      [[0, 0, 1],
       [0, 1, 2],
       [2, 1, 0]]
We want our function to return:
    -1 if the board is not yet finished AND no one has won yet (there are empty spots),
    1 if "X" won,
    2 if "O" won,
    0 if it's a cat's game (i.e. a draw).
You may assume that the board passed in is valid in the context of a game of Tic-Tac-Toe.
