Minimal Response Z-test Example

[sachaMorin]

We have this in scripts/run_real_example.py but it includes a lot of boilerplate to reproduce all the tables from the paper. I suggest we design a simpler example (e.g., with only 3-step BCH) and include it in the notebooks.

@ericlacourse @FelixLaliberte I think we discussed this already and it has been requested by users a few times. I don't have cycles to take care of this these days, but I'm happy to share access to the notebooks
