The idea is to write a notebook with pure PyMC model(s) for each of these CLV scenarios. We can start with the Lifetime part (not-value yet), but ideally we will include value as well by the end. This might be a constant with time-decay penalty in the simplest cases.

Hopefully this will give us a good picture of the building blocks that are necessary for a minimum viable package, and can also serve as the base documentation. Overtime we would replace the custom PyMC code with imports from the CLV sub-package.
