tumor_reg_data jupyter notebook based on test data

[dckc]

tumor_reg_data.py is 2-way sync'd (using jupytext) with tumor_reg_data.ipynb. I taught Jenkins to run the notebook based on test data.

I'd like to either check in the results or otherwise publish it. (ideally by teaching travis to build it...)

It lacks narrative etc., but as a demonstration, on a branch:

The run_notebook target in Makefile pretty much works, but it takes ~10 min so I don't run it very often.

I made some headway on the narrative for the first sections of the notebook, but until most of the notebook works that way, let's keep this open.

Tablesaw in notebooks looks promising too.
