Mediate conformance

What is in this package? For an adapter author proving an adapter.

The suites that hold an adapter and a mediated repo to the conformance document. Mediate.Conformance.AdapterCase runs the laws against an adapter, and Mediate.Conformance.RepoCase runs the guarantees against a repo. An adapter supplies a Mediate.Conformance.World, a repo supplies a Mediate.Conformance.RepoCase.Rows, and each template's moduledoc has the options. Add the package to the :test dependencies.
