@cmp0xff our first model is here.

Partially reviewed...

I suggest we add a short example for this, in the style of a Jupyter Notebook. Then we can conclude this first system!

We can also use Jupyter Interactive of VSCode, so that we only keep .py scripts in the repo, but users can parse them with VSCode, and we do not accidentally upload ipynb with base64 data in them to the repo... It would also be easier for me to study and follow.

update: I did not see the tutorial in the next PR when I wrote this..
