[Dune] Entity vs EntityPointer

[Christoph_Gersbacher]

Hi,

the best thing I could come up with for dune-fem is to use a 
compatibility method that always returns an entity:

    template< class Grid, class Implementation >
    typename Dune::EntityPointer< Grid, Implementation >::Entity
    make_entity ( const Dune::EntityPointer< Grid, Implementation >
    &entityPointer )
    {
       return *entityPointer;
    }

    template< int codim, int dim, class Grid, template< int, int, class
     > class Implementation >
    typename Dune::Entity< codim, dim, Grid, Implementation >
    make_entity ( Dune::Entity< codim, dim, Grid, Implementation > entity )
    {
       return std::move( entity );
    }

Then, the statement

    Intersection::Entity entity = make_entity( intersection.outside() );

will not give raise to compiler warnings no matter which grid is used. 
After the 2.4 release you can easily deprecate the compatibility method 
and find and remove all its occurrences.

Best
Christoph
