This library provides a simple method to find the normal/canonical form
of a structure, as long as it implements the provided `Normalize` trait.
It is an implementation of *Practical graph isomorphism, II*
[[McKay 2013]](https://arxiv.org/pdf/1301.1493.pdf) and heavily inspired by
the [canonical-form](https://crates.io/crates/canonical-form) crate with the
addition of caching and associated abstraction types.
