- Find out why we have separate objects CaveSlug and EntranceSlug and why
  these are not just a single field on the Model. Do we ever need more
  than one slug per cave or entrance? Surely that would break everything??
  
- Move PersonTrip to be with Person and Expedition elsewhere
  
- Restore constraint:   unique_together = (("area", "kataster_number"), ("area", "unofficial_number"))
