Player input

[Autofire]

When it is the player's turn, the player should be able to select a place to put their mark on an empty space. Obviously, they shouldn't be allowed to place a mark in a non-empty space.

Tasks

• Create behavior to alert the rest of the program when it's the human player's turn.
• Create UI to allow the player to click on an empty space.
• When a taken space is selected, either the program should ignore it or a warning message should be shown.
• Upon selecting a valid space, the player's turn needs to end.

Done

On the player's turn, they should be able to make their move without borking the program.
