scn ElevatorScript

;======================================================================================================================
; This is the quest script that moves the elevator. It will figure out which way to move automatically.
; It is passed a list of objects that make up the elevator car and its contents, it will move those items
; up or down at the interval defined in the ElevatorSpeed global.
;
; The initial location is set by linking the elevator car floor to the location ref closest to it.
;
; For the doors, the elevator floor is linked to the interior door, and the location marker is linked to the exterior.
