[MOAB-dev] exchange entity sets

[Lorenzo Alessio Botti]

Thanks, and yes, what you propose is an effective workaround!

I'll rely on this for now, but I'd like to know if you need and/or plan to introduce something like exchange_ghost_sets(...) at some point.
Such a thing would allow me to save a lot of ghost cells. 

Best regards.
Lorenzo
