Continous integration through Travis CI (#71)

* Adding Travis CI badge

* Modifying end to end tests to reflect testing against docker-compose setup in Travis CI.

* Adding bash script to run simple container with tests within bridge network for Mac.

* Adding documentation for setting up a developer environment.

* Decreasing amount of CPU needed for CreateJobWithPulse because a higher value causes Travis CI to hang.
