Project Ideas

1. Upgrade emcee to try differential evolution move to rescue stranded walkers
2. Remove ridge alpha. Ridge alpha makes sense less sense for us in this domain that does a machine learning problem because the parameters have physical meaning and making them artificially smaller doesn't make sense.
3. Change fitting step API to not have to go into the Model._dbe. This is both a code cleanliness (separation of Database and Model) and performance (no rebuilding Model).
