@nhoening suggested the following files for the `config` sub-package: - `__init__.py` - `Readme.md` - `utils.py` - `defaults.py` - `requirements.py` > The latter would be where we put the requirements we...

Just for scoping this issue, I started thinking about this from an extreme perspective: what if a plugin could register a function with completely custom parameters, and FlexMeasures would read...
