working on real collaboration

- update config structure
- fixed exit and rewind
- reread config on rewind
- read regions on both sites
- add demo commands for site B
- create svg at model-command for site-B, and publish filename
- enhance compute-operations: source location can be collaboration zone as well, add wait command when zone is not owned and occupied
- connect occupiedCollaborationZoneNames with self-loop and "moving-in" and "moving-out" logic
