Class RegionOperator

This class automatically extracts a submesh from a mesh, and can re-insert it after you have edited it, as long as you have not messed up the boundary

[TODO] Nearly all the code here is duplicated from RegionRemesher. Maybe this could be a base class for that? [TODO] ReinsertSubToBaseMapT is not returned by the MeshEditor.ReinsertSubmesh, instead we are trying to guess it here, by making some assumptions about what happens. It works for now, but it would better if MeshEditor returned this information.
