Added Travis support and removed SMARTData package

I rebased your branch with [SMART-Lab/mldata](https://github.com/SMART-Lab/mldata) to include the new CI travis.yml configs.

I removed the SMARTData package, please update your env `PYTHONPATH` to include your folder `SMARTData/` instead. When installed using `python setup.py install` or `pip install` the library `mldata` will be added to your `PYTHONPATH` automatically.
