Dear Christian,

I very much like your proposal because this is on my TODO list anyway. I
need this as part of (a soon to be publicly announced) project on automated
testing in Dune. There, we want to control the variation of system tests
through ini files mainly and solver construction definitely should be done
through a factory class that takes the parameter tree.

That being said, count me in as a mentor/co-mentor on this one. We can talk
about details next week during the dune course.

Best,
Dominic
