-Geometries in a `domain` can be accessed with a single index

-Even though it is tempting to use `domain[i,j]` and `domain[i,j,k]`

 In computational geometry, a `CartesianGrid` is a specific
 type of [mesh](https://en.wikipedia.org/wiki/Polygon_mesh).
 It can only represent "flat" domains sampled regularly along
