we have nodal laplacian. close this?

this should be there for a regular mesh not a tensor mesh.

We haven't really had a necessity to have a general laplacian operator. Also the point of expressing the finite volume form of the system is to try to avoid taking higher order derivatives directly. Some meshes do already have a nodal_laplacian though (the regular structured meshes).
