remove generic geometry subdirectory
On the last developer meeting, we agree on the following things:
- The
genericgeometry
subdirectory should vanish in the next DUNE release. - All content of the namespace GenericGeometry is considered an implemenation detail.
This merge implements these decisions. All functionality that is sitll required is migrated into the appropriate headers in dune/geometry
and put into the namespace Impl
.
Note: There is no transition phase for the content of the genericgeometry
subdirectory.
