Title: New sandbox example: 5 NBin variations

As discussed on the mailing list. The new semester is coming and I will probably forget about this file, so I thought I would PR this as a sandbox example for now. Sandbox was suggested as a possible destination by Josef on the mailing list.

I may eventually be able to invest more in this, so let me know if you have ideas for a path forward. For instance, analytical derivatives and hurdle + zero-inflated models seem like good candidates for future work.
