-            - Castling Rights
-          - Side to move
-        - Square of en passant, if available
-        - Zobrist hash
-- `"move" <move>`
-    - makes a move
-    - Standard Algebraic Notation(FIDE notation)
-    - Square is a file (a-h) and rank(1-8)
-    - Promotion piece is either, q(queen), r(rook), b(bishop), or n(knight)
-- `"undo"`
-    - Undo the last move that was made
-- `"eval"`
-    - Prints the static evaluation of the position
