rfm_train_test_split for CLV model evaluation

[TianruiZhang]

Is there an example showing how rfm_train_test_split used in the evaluation of a CLV model like BG/NBD model? I assume model evaluation on unseen data would be necessary for any CLV models like BG/NBD to avoid overfitting, right? Since rfm_train_test_split was just released, there is no code example, anyone please give an example.

I have planned a more comprehensive notebook for evaluating marketing campaigns which will involve rfm_train_test_split, but for now I've created a PR adding a quick example to the Quickstart.

MCMC models are more robust against overfitting than those fit with MAP. Train/test splits are typically only needed for the latter.
