This is the server-side implementation of the Avers storage model. It is a
Haskell library, intended to be used by your application. The library provides
you with everything you need to write your own Avers server. You can create and
patch objects and collections thereof. It has builtin support for sessions,
authentication and managing blobs. The database is not configurable. Avers is
currently hardcoded to use RethinkDB.
