Split grid manager specialization into different headers
Problem: When updating the code of a grid manager, all tests have to be recompiled, not only the tests that use this particular grid manager. Example: I pull an upstream bugfix in dune-foamgrid, everything has to be compiled again, not only the tests using foamgrid.
Each specialization of
Dumux::GridManager could go in its own header (which includes the base definition and header for this particular grid manager)
- Disadvantage: You would need to change your includes if you use a different grid manager
- Advantage: Only the code for grids that are actually used has to be included. Update of a grid manager only affects those applications that really use this grid manager
