Subsequently writing the grid to a file with VtkWriter yields a file with many additional vertices all at coordinates (0,0,0).
The simplest fix is to only cache the vertices in `insertVerticesImpl` and insert them into the factory later in `insertElementsImpl` selectively just like `LagrangeGridCreator` does it.https://gitlab.math.tu-dresden.de/iwr/dune-vtk/-/issues/1Periodic YaspGrid2018-08-28T16:20:58ZPraetorius, SimonPeriodic YaspGridThe structuredGridWriter has problems with periodic YaspGrids.
