# This script is intended to be bound to event objects in order to conditionally trigger
# connections based on the status of a quest, used correctly it can reduce the need for
# markers to use checkinvs on.
# it must always be given the following arguments:
# name of the quest
# stage(s) to trigger on
# connection to trigger
# the quest must exist, and the connection must be present on the map.
