// According to https://docs.rs/ndarray/0.16.1/ndarray/struct.ArrayBase.html,
// "The default memory order of an array is row major order (a.k.a “c” order),
// where each row is contiguous in memory." This means we can use the default
// implementation of PartialOrd and Ord. If we were using column-major ordering,
// we would need to implement an ordering that prioritized the y value over the
// x value.

// It would be nice to unify BoundaryIndex and GridIndex into one type that
// can be sorted and also directly used by ndarray's indexing operations.
