TPW PARK - Ambient parked cars for Arma 3

Author: tpw
Requires: Community Base Addons A3

Description
-----------
This mod adds parked cars to roads near habitable houses, in a dynamic and CPU friendly way.

	- Spawns parked cars within a defined radius of player.
	- Cars are spawned near a defined percentage of habitable houses, up to a specified maximum.
	- Cars spawn onto the side of the road, facing the correct direction.
	- Cars are hidden/removed if beyond a specified distance from player.
	- Cars are set enablesimulation false to minimise FPS hit. In this state they have no physics, cannot be destroyed, driven etc.
	- Cars are set enablesimulation true only if player is nearby or any member of player's squad is a driver.
	- Cars are spawned with random fuel.
	
Known issues
------------
By default vehicles chew up a lot of CPU due to their high poly count and more importantly the demands of PhysX and other aspects of their simulation. Even when not being driven, an editor placed car is hitting the CPU. Don't believe me? Place 20 empty cars in the editor and watch your FPS take a dive. TPW PARK gets around this in several ways: by only spawning cars near the player; by hiding those beyond a certain distance; and most importantly by disabling the simulation for each car unless the player or squad is actually driving it. While this approach allows for cars without a terrible FPS hit, it does have some limitations

	- Vehicles will pop in occasionally. Particularly if you are driving. And of course if you teleport to a location (in which case I'm not interested in complaints about lack of realism).
	- Vehicles will occasionally spawn onto a structure and explode, despite my best efforts. All spawned vehicles are monitored and removed within 0.1 sec if they register any damage. 
	- The default values should spawn a handful of cars around the player in a decent sized village/town. Resist the urge to dial up all the values for dense parked cars as far as the eye can see. The CPU will not thank you.
	- Simulation disabled cars cannot be damaged. You can flatten a town and the cars are still shiny.
