More tools for regression tests
New ideas for regression tests. It should be possible to ignore changes at let's say a saturation front, maybe by allowing a certain number of dofs to have a error higher tolerance. Another idea would be to map the solution of an adaptive grid to some reference grid and compare the solution there (we have some L2-projection capabilities now (only 2d for non-matching grids)).
What does this feature / why does DuMux need it:
It would make it possible to create more robust tests in cases where this is desired / physically-sensible.
