Bitemporal Anchor Modeling

Bitemporal Anchor Modeling is now ready for testing in the latest test version. The last piece of the puzzle, bitemporal relationships (ties), have now been added as well. I believe there is little need for triggers on the ties. Let us know if you think otherwise. The following views should be available on all ties, where l = latest, p = point-in-time, d = difference, and the first position for changing (valid) time and the second for recording (transaction) time:

ll, lp, pl, pp, dl

The other combinations, such as ld, pd, etc, have been considered of less use and may be added at a later time. Once this version has been tested and deemed stable, it will be pushed to release status.
