Post-processing mesh subset tool. Given the original mesh and the list of selected cells, it creates the mesh consisting only of the desired cells, with the mapping list for points, faces, and cells. Puts all exposed internal faces into either - a user supplied patch - a newly created patch "oldInternalFaces" - setCellSubset is for small subsets. Uses Maps to minimize memory. - setLargeCellSubset is for largish subsets (>10% of mesh). Uses labelLists instead. - setLargeCellSubset does coupled patch subsetting as well. If it detects a face on a coupled patch 'losing' its neighbour it will move the face into the oldInternalFaces patch. - if a user supplied patch is used the mapping becomes a problem. Do the new faces get the value of the internal face they came from? What if e.g. the user supplied patch is a fixedValue 0? So for now they get the face of existing patch face 0.
