Added voronoi2.ipynb which is a reformatting of the old voronoi2.ipynb. It contains a plot of the various state decompositions. In order to run it again, you will need to install either all of github.com:schwancr/schwancr_bin or just grab github.com:schwancr/schwancr_bin/pyschwancr/custom_tickers.py because I use that to format the log likelihoods in the figure.
