This code is part of a spatial-information processing system, described here: https://wiki.opencog.org/w/SpaceServer

The actual implementation status of this code is unclear. I think it works. I think parts of it have unit tests. I think parts of it might be correctly designed and implemented. Parts of it might be incomplete or incorrect or not needed. It might need changes to the API to become fully useful. The code here needs:

• An active maintainer!
• A full design review!

This subsystem stores Atoms in a 4d spacetime coordinate map. The current or past location of an atom can be queried, as well at the set of atoms at a given location or time.

Scheme bindings are provided by the (opencog pointmem) module.
