[Dune] Layout::contains and boundaryId

[Dragan Vidovic]

Hi all

I use a mapper to map all codim 1 entities, but I'd like to exclude
all entities where a certain type of boundary condition was
prescribed, i.e. where boundaryId has a certain value. However, since
only the grid dimension and the entity's GeometryType are passed to
the Layout::contains method, I don't see a way to determine the
boundaryId inside this method. Is there any way to do this?

Thanks,

Dragan
