[dune-pdelab] Implementing OVLP_AMG_4_DG solver

[Lukas Riedel]

Hi Christian,

the source of the problem was not related to PDELab:
I used the StructuredGridFactory to build an instance of YaspGrid, but it creates a grid with an overlap of 0.
After using the default constructor of YaspGrid (overlap 1), the solver performed as expected.

Thanks and cheers,
Lukas
