Description

Initialisation values for one model (Richards equation) are already well stablished. When adding more models to dorie, it is easy to ask for a ini file for the respective model (see #101 (closed)), however, this approach is not maintainable in time since dune-testtools can't handle several inifiles. Therefore, we have to find a workaround for this.

Proposal

Modify the current ini file so that it can accept values for several models.

• Define API
• Split xml files according to the model
• Allow parser scraper to recognize different models
  • Restructure folders structure

Here are our current inifile as a reference:
