  Thin facade that dispatches storage operations to the configured adapter.

  This module isolates the rest of the code base from the concrete
  storage implementation. By default the `Subaru.Store.Mnesia` adapter is
  used, but this can be changed via the `:subaru` application environment:

      config :subaru, :store, Subaru.Store.Mnesia
