//! Models a game of [coinche](https://en.wikipedia.org/wiki/Coinche) (a french card game).
//!
//! See [coinched](https://github.com/Gyscos/coinched) for an example of usage.
//!
//! Here is a simple example:
//!
//! ```rust
//! extern crate libcoinche;
//! use libcoinche::{bid,cards,pos};
//!
//! fn main() {
//!     // The first player
//!     let first = pos::PlayerPos::P0;
//!
//!     // Start the first phase with an auction
//!     let mut auction = bid::Auction::new(first);
//!
//!     // Check their cards
//!     let hands = auction.hands();
//!
//!     // Players bid or pass
//!     auction.bid(pos::PlayerPos::P0, cards::Suit::Heart, bid::Target::Contract80).unwrap();
//!     auction.pass(pos::PlayerPos::P1).unwrap();
//!     auction.pass(pos::PlayerPos::P2).unwrap();
//!     // The result is `Over` when the auction is ready to complete
//!     match auction.pass(pos::PlayerPos::P3) {
//!         Ok(bid::AuctionState::Over) => (),
//!         _ => panic!("Should not happen"),
//!     };
//!
//!     // Complete the auction to enter the second phase
//!     let mut game = auction.complete().unwrap();
//!
//!     // Play some cards
//!     game.play_card(pos::PlayerPos::P0, hands[0].get_card());
//!     // ...
//! }
//! ```
