Suggestion: GridGraph

[simonschoelly]

Maybe it would be nice for numerical problems to have a graph that represents a multidimensional grid. Then there should be a way to access the vertices not only with an integer, but also with an instance of CartesianIndex.

I see yes that would be interesting. Thing is, not sure we can represent infinite grids (what should nv and ne return?) but finite grids should be fine

[simonschoelly]

I wouldn't do infinite graphs, just finite grids, maybe with the possibility to wrap around.
