ucvm seems to supersede UCVMC

[baagaard-usgs]

It looks like the ucvm repository supersedes the UCVMC repository, but there is no indication in the README.md or elsewhere in the UCVMC repository that it is not the current implementation for the UCVM software.

If the ucvm repository is the current repository for the UCVM software, please add a prominent notification on the UCVMC repository that ucvm is the current implementation for the UCVM software. I also suggest migrating any issues that still exist to the current repository.
