Napkin.Run.Effects.Interpreters.FakeLocal

Description

A SqlBackend interpreter that performs a minimal amount of table state management to facilitate dry runs and trivial unwrapping of SqlBackend effects.

It produces a report of used depedencies, but this is not intended for use in the Spec system for figuring out dependencies. User's forced/added dependencies would not show up here, for example. This is meant more for dry runs and simulations.
