v1.3.0 Trap fixes

This patches flawed logic when capping pieces.

v1.2.0 Library target

This release contains no new game logic.

• Projects depending on this no longer have "clap" as a transient dependency.
• Board is now iterable for (coord, tile) such that it can be used by other projects.

v1.1.0 AI difficulty can be adjusted

this minor patch adds the --horizon flag which defaults to 3. this flag adjusts the search depth for the AI so a lower value makes an easier game. Higher values than 4 seem to slow down the game.

v1.0.0

Can now play against an AI and start either as red or blue.
Default is to play against a human player.

0.1.0

First version, only Linux x86.
