//! # Token trait and blanket impl
//! ## Rationale
//! This makes it easier to define required trait bounds,
//! rather than using the long form.
//!
//! The reason for each trait is as follows:
//! * Clone - This is a useful utility trait to implement. It makes it easier to
//! build an Abstract Syntax Tree without dealing with references and
//! lifetimes.
//! * Debug - Necessary impl for failure::Fail trait
//! * Display - Necessary impl for failure::Fail trait
//! * PartialEq - Necessary impl for the consume method in GeneralParser
