Initial commit

This is a service designed to provide information about Guix. At the
moment, this initial prototype gathers up information about packages,
the associated metadata and derivations.

The initial primary use case is to compare two different revisions of
Guix, detecting which packages are new, no longer present, updated or
otherwise different.

It's based on the Mumi project.
