Draft: Feature/hldd
What this MR does / why does DuMux need it:
Our software needs a high-level design document because it's like a blueprint that helps everyone on the team get on the same page about how DuMux thing is put together and works. Corresponds to #1154
Notes for the reviewer
Before you request a review from someone, make sure to revise the following points:
-
does the new code follow the style guide? -
do the test pipelines pass? (see guide on how to run pipelines for a merge request) -
is the code you changed and/or the new code you wrote covered in the test suite? (if not, extend the existing tests or write new ones)
