--- Route programming system

-Progamming routes:
-1. Select "program new route" in the signalling dialog
--> route_start marker will appear to designate route-program mode
-2. Do those actions in any order:
-A. punch a TCB marker node to proceed route along this TCB. This will only work if
- this is actually a TCB bordering the current TS, and will place a
- route_set marker and shift to the next TS
-B. right-click a turnout to switch it (no impact to route programming
-C. punch a turnout (or some other passive component) to fix its state (toggle)
- for the route. A sprite telling "Route Fix" will show that fact.
-3. To complete route setting, use the chat command '/at_program_route <route name>'.
- The last punched TCB will get a 'route end' marker
- The end of a route should be at another signal facing the same direction as the entrance signal,
- however this is not enforced and left up to the signal engineer (the programmer)
-
-The route visualization will also be used to visualize routes after they have been programmed.
