[Dune] processor boundaries on nonoverlapping grids

[Bernd Flemisch]

Hey Alex,

you can ask an entity for its PartitionType, see
http://www.dune-project.org/doc/doxygen/dune-grid-html/group___g_i_related_types.html#gbd89b77709db1d9e56bb17cd0aa44c3d 

and
http://www.dune-project.org/doc/doxygen/dune-grid-html/class_dune_1_1_entity.html#a359da1ebacea2d961f2ceb74250aebe

So for the entity in question just ask something like
if (entity.partitionType() == Dune::GhostEntity)

Kind regards
Bernd
