Overview

Package files defines a Provider that stores all data in the filesystem

We assume the same validator hash may be reused by many different headers/Commits, and thus store it separately. This leaves us with three issues:

1. Given a validator hash, retrieve the validator set if previously stored
2. Given a block height, find the Commit with the highest height <= h
3. Given a FullCommit, store it quickly to satisfy 1 and 2

Note that we do not worry about caching, as that can be achieved by pairing this with a MemStoreProvider and CacheProvider from certifiers
