Draft: Feature/dashboard

The goal is a dashboard, that enables

1. a quick overview of result files or scenarios (like in the screenshots below), and
2. display the code used for it, to enable a better quickstart into results analysis.

It uses streamlit, which can be

• installed with pip install streamlit and
• run with streamlit run app.py (on this branch, where app.py exists)

Any suggestions are highly welcome.
