[Dune] Gmsh reader crashes when using the grid factory read for ALUSimpleGRid<3, 3> with boundary id's

Hi Benedict,
that is because Gmesh uses a method on the Factory which is non standard 
- and
not implemented in this form in ALU.
As I see it, the gmsh reader can not be used with ALU if boundary ids 
are required.
