## Detailed Description

Spatially partitions points using a parallel radix-based sorting algorithm.

Performs a stable deterministic sort; partitioning the same point sequence will produce the same result each time.

The algorithm is unbounded meaning that points may be distributed anywhere in index space.

The actual points are never stored in the tool, only offsets into an external array.
