Function ARVRController.controllerId
The controller's ID.
A controller ID of 0 is unbound and will always result in an inactive node. Controller ID 1 is reserved for the first controller that identifies itself as the left-hand controller and ID 2 is reserved for the first controller that identifies itself as the right-hand controller.
For any other controller that the ARVRServer detects, we continue with controller ID 3.
When a controller is turned off, its slot is freed. This ensures controllers will keep the same ID even when controllers with lower IDs are turned off.
