Add tests and Travis CI

[jaimergp]

Hi!

I have written a small test suite with py.test and added the necessary files for enabling Travis CI automated testing. That way any future forks and PRs can check quickly if they are breaking something or not. The main repo should be enabled https://travis-ci.org/, but other than that, it's pretty much pre-configured.

I did this because I am thinking of a deeper PR (current development here ), but that's another discussion :)

Let me know what you think!

First commit 9ccd2cf can be ignored. It's from a previous attempt and somehow reappeared here.

Hi, thanks for the merge!
For this to be functional, you have to sync your GitHub account at https://travis-ci.org and enable this repository. After that, you would probably want to edit the README.md so the Travis badge points to https://travis-ci.org/bobbypaton/GoodVibes instead of my fork.
Once that's done, any further PRs and commits will benefit from the automated testing in Travis :)

Many thanks for this - looks like this is now working!
