Figure out setting up coo as part of a CI process

It would be best if it were possible to generate the docs as part of CI and commit them there once tests pass. Would be good to set up and document.

This is partly done, but I need to document it, now.

Images are built on push by quay.io and I've figured out a recipe for travis, at least. Would welcome others as they get figured out.

Here is another way to build documentation with Coo and GitHub actions. Docker is not required:
