	Description:
	Random flyby

  Note:
  If you using custom code, you need to delete the crew and vehicle by yourself !

	Parameter(s):
		0 Optional: Classname of the vehicle or Array of Classnems, crew will be created automaticly
      Recommend to only use planes or helis

    1 Optional: Custom center, Type object

    3 Custom code passed as array [{1},{2}]
      1) Code on start waypoint
        Access the vehicle with _vehicle = param[0];
      2) Code on end waypoint
        Access the vehicle with _vehicle = param[0];

        To only use waypoint end code use [{},{code}]

----------------------------------->

    Examples:

    o) Basic

      []execVM "fox_ambientFlyby.sqf";

    o) Advanced

      [
        ["C_Heli_Light_01_civil_F","B_Plane_CAS_01_F","O_T_VTOL_02_infantry_F"],
        false,
        [
        {
          _smoke = "SmokeShellGreen" createVehicle [0,0,0];
          _smoke attachTo[_this select 0,[0,0,0]];
        },
        {
          {deleteVehicle _x;} forEach crew (_this select 0);deleteVehicle (_this select 0);
        }
        ]
      ]execVM "fox_ambientFlyby.sqf";

----------------------------------->

    You can copy pasta the code below directly in the 3den debug window to test it.
