//!
//! [`EGraph`]s (and almost everything else in this crate) are
//! parameterized over the language given by the user (by implementing
//! the [`Language`] trait).
//!
//! A typical usage would either implement [`Language`] or use the
//! provided [`TestLang`]. From there, you can use the functionality
//! from the [`ParsableLanguage`] trait module to create expressions
//! and add them to the EGraph.
