# 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.
# Usage: /python/quests/QuestTriggerConnect.py QUEST STATE CONNECTION [EDGE]
#  QUEST - quest identifier string
#  STATE - stages to trigger on
#  CONNECTION - connection number
#  EDGE - optional trigger edge, 1 (release) by default
