A finite volume solver.
This solver is not appropriate to simulate black holes as a stand-alone solver, as it is way too diffusive. If you use it without another scheme, you typically see the black hole disappear after a brief period. So we have it in here merely for performance tests.

| name, | |||
| patch_size, | |||
| min_cell_size, | |||
| max_cell_size ) |
Construct the Finite Volume solver.
| patch_size | Integer Defines how big the individual patches are. If you pass in 10, each Finite Volume patch will have the dimensions 10x10x10. |
| min_cell_size | Float This parameter refers to the cell size, i.e. the size of a whole patch. We use this one here, to make the signature the same as for the FD and DG solver variants. The superclass constructor argues over finite volume sizes, and we hence have to recalibrate this parameter with patch_size. |

Tailor action set behaviour.
We first make a few additional cells skeleton cells. The rationale behind additional skeletons is given in the generic overview. Given the first remark there on FD4-FV coupling, one would be tempted to use the predicate
Once we study the other items (notably the fourth), we see that it is reasonable to make all the overlap region a skeleton within the FD4 solver.
