It would be nice to implement some number theory functions such as the extended GCD, the modular inverse and the modular power. See https://github.com/vks/discrete-log/blob/master/src/main.rs for a generic implementation that could probably be implemented more efficiently inside this crate.

There is now direct support for modular arithmetic with the ModuloRing type.
