Recheck all notebooks are working and using the most recent PyRolL versions.

In the README here we could also setup a table to list all notebooks, when they were last checked to be working, who checked them, which version of PyRolL they were used on, etc.

Missed what you were writing Richard. Yes that's a good idea.

What is the current state here, someone still working on it?
