/*
* Author: Pabst Mirror (based on Explosive attach by Garth de Wet (LH))
* Approves placement of the lightObject, scans for an appropriate location and attaches
* A player can release the attachObject with it floating in mid-air.
* This will use lineIntersectsWith to scan towards the center of the vehicle to find a collision
* ArmA's collision detection is of couse terrible and often misses collisions (difference between what we see and collision LOD)
* So it does multiple scans at slighly different angles
* This is VERY computationaly intensive, but doesn't happen that often.
*
* Arguments:
* 0: Unit (player) <OBJECT>
* 1: attachToVehicle <OBJECT>
* 2: Item Classname (CfgWeapon/CfgMagazine) <STRING>
* 3: Light Vehicle Classname <STRING>
* 4: On Attach Text <STRING>
* 5: Starting Pos of dummy item <ARRAY>
*
* Return Value:
* None
*
* Example:
* No
*
* Public: No
