@cesswairimu Let's get this Travis thing to run "locally", what do you think?? I'm Mapknitter we got the tests to run ~2x faster. Let me work with that on top of this branch?

We set the jobs to properly run in parallel, include a stage where can remain testing the docker building, including some gem caching....
