constants
enumset: A library for defining enums that can be used in compact bit sets. It supports arbitrarily large enums, and has very basic support for using them in constants.

BitBoard: A bitboard is a value type wrapping a 64 bit integer which represents a set of squares on a chess board. Each bit is mapped to a particular square on the board, 0 -> H1, 1 -> G1,…, 8 -> H2,…, 63 -> A8. For example if we know a piece to reside on a particular square we can use a bitboard to to capture the available moves for that piece.
Board
EvalBoard
MaterialParameters: Allows one to configure the parameters of the evaluation board.
PieceValues
PositionTables
SearchOutcome: Data class composing information/result about/of a best move search.
SearchParameters
UciMove: String wrapper representing a chess move formatted using the uci standard. We can use this to reflect moves outside the context of a board.

CastleZone: Represents one of the four different areas on a chessboard where the special castling move can take place (two for each side).
Dir: Type representing a square on a chessboard.
FenComponent: Represents the individual components which make up a board position encoded as a FEN string.
Move
MoveComputeType
Piece: Value type wrapping a single integer representing one of the 12 different pieces in a game of chess.
Side: Represents the two different teams in a game of chess.
Square: Type representing a square on a chessboard.
Termination: Represents the possible ways a game can be terminated, we only consider a game to be terminated when a side has no legal moves to make or if a special draw condition is met like position repetition. If a side has no legal moves and is currently in check then the game is lost, if it is not in check then the game is drawn.

ChessBoard: Trait representing a mutable state of play of a chess game which can be evolved/devolved via (applicable) Move instances, compute the set of legal moves and queried for a variety of properties.
EvalChessBoard: Extension of the Board trait which adds a static evaluation function.
Reflectable: Chess is a symmetric game and this trait represents a component of the game which can be reflected to it’s symmetric opposite component.
SearchTerminator: Represents some object which can determine whether a search should be terminated given certain context about the current state. Implementations are provided for Duration (caps the search based on time elapsed), for usize which represents a maximum search depth and for a pair (Duration, usize) which combines both checks.

search: API function for executing search on the calling thread, we pass a root state and a terminator and compute the best move we can make from this state within the duration constraints implied by the terminator.
start: Return the start position of a standard game
