Make tutorial interactive

The static version on nbviewer is nice, I would suggest an extra link to http://mybinder.org/, which would allow to run the notebook in the cloud (as long as there are containers available) and would be even easier to set-up for beginners.

Seem to be a bit flaky today. Usually works great.
