BD Building Patrol Script

Description
The purpose of this script is to allow AI units to patrol inside of a building. Contrary to popular belief, the ArmA2 AI works very well indoors. This script allows you to set up a path for them to patrol using buildingPos's. When the unit reaches a waypoint, he will wait there for a short period of time before moving on. In addition, (optionally) he will watch a specified direction at that waypoint. The unit will move to the waypoints in order, and will loop when the last waypoint is reached. When the unit becomes alerted they will move more cautiously, and (optionally) will move to a specified position until they resume SAFE mode, at which point they resume the patrol. You can also cease the patrol by passing the script a condition. By ceasing the patrol you can allow the unit to move freely, leaving the building, whatever you want. Once the patrol is ceased the script terminates, so you have to execute it again to resume the patrol afterward.
