EN-01 About Documentation

[xoloki]

In auditing this project we also went through some alternative FROST implementations. We found the ZF Frost Book that accompanies the Z-Cash implementation to be helpful and suggest writing an analogous text. References to the FROST and WSTS papers, or the IETF standard are also welcome.
Documentation for relevant use cases is missing. In particular, there is no clear indication into what the interfaces that the library exposes to users since all functions are public. The most relevant files and functions should include more detailed documentation.
We also find that examples would complement very well with the code and provide a concise guide to library users (developers).
