Should `matplitlib` be added to (optional) dependencies in `setup.py`?

[StephanDeHoop]

It seems like running examples\PoCTutorial\src\run_municipality_roll_out.py out of the box (after installing mesido (with pip install -e .) fails to run due to missing matplotlib dependency). Could it be added to the setup.py either as additional or optional dependency (with some flag associated with it if you want to run examples that require plotting)?

See stacktrace below

I installed the optional dependency of course, but maybe it is easier to just add it to the setup.py?
