      Description

      In discussions with Michelle Gower about temporary-scratch-repo use cases, we identified that it would be nice to have a Registry implementation that supports only generalized get and put (not expressions), and hence does not need DataUnit tables.  This is similar in functionality (but not implementation) to a previous LimitedRegistry concept that we envisioned not using SQL at all; the new concept would use SQLite, but would have only a subset of the full Registry schema.

      Whether there are any non-DataUnit tables we could drop from LimitedRegistry is an open question; one possibility is that it could also only represent a single Collection, and hence have no need for DatasetCollection either.

            Tim Jenness, I'm afraid you're going to start getting roped into reviewing more and more Registry tickets now.  I think this is a pretty straightforward one, especially if you go commit-by-commit.

            Michelle Gower may also want to take a look as she was the one who requested this functionality.  Right now limited Registries only differ from full ones in that they don't have or need DataUnit entries or joins.  I thought about having them only ever use one Collection, but that would a bigger change for smaller gain; some methods would have to be work differently in limited mode, rather than just not working at all.

            Looks fine. Minor comments on PR.
