Features
--------

* Generate legal moves:

  ```rust
  use shakmaty::{Chess, Position};

  let pos = Chess::default();
  let legals = pos.legals();
  assert_eq!(legals.len(), 20);
  ```

* Play moves:

  ```rust
  use shakmaty::{Square, Move, Role};

  // 1. e4
  let pos = pos.play(&Move::Normal {
      role: Role::Pawn,
      from: Square::E2,
      to: Square::E4,
      capture: None,
      promotion: None,
  })?;
  ```

* Detect game end conditions: `pos.is_checkmate()`, `pos.is_stalemate()`,
  `pos.is_insufficient_material()`, `pos.outcome()`.

* Read and write FENs, SANs and UCIs.

* Supports Standard chess and Chess960. Provides vocabulary to implement
  other variants.

* Bitboards and compact fixed shift magic attack tables.
