Document the library in Dredd docs

[honzajavorek]

It was suggested to me by @kylef we could document the public interface of this library using Sphinx JS. I think it is an awesome idea.

We'll just need to figure out how to get Dredd Transactions code and doc files when building the Dredd docs, since these two projects are separate beasts and not a monorepo.

@michalholasek I think monorepo would easily allow this 👍

[michalholasek]

@honzajavorek Yes, it would 🙂

This issue has been moved to dredd as a part of preparations to move dredd-transactions into Dredd's monorepo.
