/**
@author Bastiaan Olij <mux213@gmail.com>
The positional tracker object as an object that represents the position and orientation of a tracked object like a controller or headset.
An AR/VR Interface will registered the trackers it manages with our AR/VR server and update its position and orientation.
This is where potentially additional AR/VR interfaces may be active as there are AR/VR SDKs that solely deal with positional tracking.
@TODO:
- create subclass of spatial node that uses one of our positional trackers to automatically determine its position
