Update deal.II scripts

Related to precice/dealii-adapter#50 and precice/dealii-adapter#51.

@uekerman Now you have an example for the new version. I hope this helps in order to review the changes. In the dealii-adapter, please review first precice/dealii-adapter#51 and then precice/dealii-adapter#50.

This review includes precice/dealii-adapter#50 and precice/dealii-adapter#51

I did not check the code details, but the user side is nice. Much easier to handle now 👍
I was able to run linear and non-linear.
Only a few things we could document better in the parameters file.
(why is there a parameters.prm in the adapter repo?)

And the README of the adapter needs to be updated.

It's needed to run a self created case.

Done.

You could also point to the tutorials, right? In the end, it's just some code duplication, so another place to update when things change. Or what do you mean by self created case? You will always need another participant and a precice-config.xml, right?

hm The way I think of it is more a parameter file reference, similar to our xml reference. The cases in the tutorials are special configurations for a certain example. In fact, I could remove half of the parameters, where the nonlinear solver is not supposed to be used.
