//! Probe Syzygy endgame tablebases.
//!
//! Syzygy tables allow optimal play under the 50-move rule. Tables are
//! available for positions with up to 6 (and experimentally 7) pieces.
//!
//! # Example
//!
//! ```
//! # extern crate failure;
//! # extern crate shakmaty;
//! # extern crate shakmaty_syzygy;
//! #
//! # use failure::Error;
//! use shakmaty::Chess;
//! use shakmaty::fen::Fen;
//! use shakmaty_syzygy::{Tablebases, Wdl, Dtz, Syzygy};
//!
//! # fn try_main() -> Result<(), Error> {
//! let mut tables = Tablebases::new();
//! tables.add_directory("tables/regular")?;
//!
//! let pos: Chess = "8/8/8/8/B7/N7/K2k4/8 b - - 0 1"
//!     .parse::<Fen>()?
//!     .position()?;
//!
//! let wdl = tables.probe_wdl(&pos)?;
//! assert_eq!(wdl, Wdl::Loss);
//!
//! let dtz = tables.probe_dtz(&pos)?;
//! assert_eq!(dtz, Dtz(-59));
//!
//! #     Ok(())
//! # }
//! #
//! # fn main() {
//! #     try_main().expect("success");
//! # }
//! ```
