Rewrote a lot of the rules file, because I had made a few big big big mistakes.

Now testing and trying to figure out the issue with Markus's Scenario 5.
Fixed Markus's Scenario 5

The problem was that you had "gestion" and "test" as postes, which
didn't actually exist.

This led the program down some wacky reasoning paths, sinec bob and
carole were now in none of the postes.
