I think the most important question is to figure out what API people want
to interact with for staggered grids since that will guide the
implementation. Staggered grids are unfortunately more dimension-dependent
than non-staggered, so 2D versus 3D issues are more complicated. How would
people like to address edge and face spaces in 3D?
