Continuous integration testing #28
Description
In principle we should be able to setup automatic testing with Travis similar to how we set it up in OpenFermion core. The main issue is that this requires a method of automatically installing pyscf. I would rate this as a very high priority. @sunqm is this something you can help with? Since you are an expert in pyscf installation, perhaps you can get this to work. If so, I can give you admin to the repo to set this up.
