Running it locally with instructions from #111

Scala API works like a charm, will try PySpark as well

@erizocosmico make docker-build fails for me on this branch while following https://github.com/mcarmonaa/spark-api/tree/fix/doc-project-name#build-and-run-docker-to-get-a-jupyter-server

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /opt/python-engine/
The command '/bin/sh -c pip install -e /opt/python-engine/' returned a non-zero code: 1
make: *** [docker-build] Error 1

error: package directory 'sourced/spark' does not exist - is that something wrong on my dev env (do not have any global python packages installed) or could be related to package rename?

Same command on master branch works for me.
Wonder why CI is green - I guess, on tag release it would have failed the same.

Just noticed that history has been re-writted and I was using b2a31b6 instead of now latest 0967d11 :/

Latest version builds like a charm!

[bzz]

Example notebook in docker and ./spark-shell work very well! 🎉

Shall we merge it?
