added dev status

NACK, the patch series is not yet ready for merge. The README statement added is not substantiated by the state of the code.

• There is no designation of the versions of CASE or UCO supported. I recommend a Git submodule pointing to CASE at the prototype release commit (3718ddf), with the submodule housed at /dependencies/CASE.
• There is no __version__ variable in any file under the /src directory.

This stumbles into a support level we hadn't documented in our policy page, but looks to me like a "Pre-alpha" status because the code doesn't do the above two items.

This PR doesn't pass my review unless it sets development status to pre-alpha, or the code is modified to satisfy the alpha status requirements.
