> I've been tinkering with a new Point-based {{RangeField}} for indexing
> numeric ranges that could be useful for a number of applications.
> For example, a single dimension represents a span along a single axis such as
> indexing calendar entries start and end time, 2d range could represent
> bounding boxes for geometric applications (e.g., supporting Point based geo
> shapes), 3d ranges bounding cubes for 3d geometric applications (collision
> detection, 3d geospatial), and 4d ranges for space time applications. I'm
> sure there's applicability for 5d+ ranges but a first incarnation should
> likely limit for performance.
