Description
Implement a way for the GameState to keep track of the legality of castling and if en-peasant is an option

Suggestions

• use two boolean values in state to track legality of castling to either side and let ApplyMove change these as rules dictate.
• remember the last move performed to enable en-peasant check.
  • have delegate to check if any en-peasant is possible
  • let the last move be public so move generators can look up which piece is eligible for the move

Implement a simple game loop in GameController

Implement methods that translate the internal model to x-board compatible outputs. The commands and format rules can be found in the XBoard documentation.

At minimum the following commands need to be implemented for the game to function:
Commands to the AI

• new
• quit
• MOVE

Commands to XBoard

• move MOVE
• Error (ERRORTYPE): COMMAND
• RESULT {COMMENT}

Additionally implementing the commands below would be preferable and make testing easier:
Commands to the AI

• post
• force + go
• sd DEPTH
• st TIME and/or level MPS BASE INC
• result RESULT {COMMENT}

Cammands to XBoard

• debug + # COMMENT
• Illegal move (REASON): MOVE
• telluser MESSAGE / tellusererror MESSAGE
• output for when in post mode, formated as ply score time nodes pv

Implement members in the Move struct that will allow for the non standard moves such as:

• en-peasant
• castling
• pawn promotion
