Clean up trustregionsolver for use with or without dune-parmg - less compiler flags
Use interiorBorder overlap, this is the correct overlap for the parallel solver
Use process number for the tapes in ADOLC, important in case ADOLC has to write a tape to disk then no two processes use the same file
Add parameter dampening in the parset-file
Remove duplicate outputs, only print on one process
Add two test parset-files for testing parmg-computations
