Unit Tests, Travis CI

In this commit I added unit tests for the exposed API endpoint methods. I added travis CI, so that it builds each time a new commit . And I have a small fix for minikube as well. Some helper methods and ordering was needed in provenance.go, like a String() change and an ordered_map type.
