I agree that `hilbertValues` is a better name. But I think that `localDataset` works fine and since we decided that we should add something like `InsertPoints()` into `RectangleTree` we have to update `hilbertValues` on each insertion/deletion. Right now `localDataset` does not require that. What do you think about it?
