Can we add this now and move to a PR system?

@mmorale3 can you (or one of your team) add a miniafqmc/testing directory for whatever you want to be checked during CI? Essentially, I need a script that will exit with a '0' for CI success, and non-zero to indicate failure. You can see what we did for miniQMC in miniqmc/testing.
