We reuse the grid creation facility of the facet coupling framework and require grid files that have the information on the fracture facets in them. This enables us to reuse the codimension one grid adapter of the facet coupling framework to identify which matrix element facets coincide with a fracture.
This also introduces a test on the same geometry as in the 2.12 release.
reintroduce tests for quads
reintroduce tests for tetrahedra
