The ARVR interface is a template class ontop of which we build interface to differt AR, VR and tracking SDKs.
The idea is that we subclass this class, implement the logic, and then instantiate a singleton of each interface
when Godot starts. These instances do not initialize themselves but register themselves with the AR/VR server.
If the user wants to enable AR/VR the choose the interface they want to use and initialize it.
Note that we may make this into a fully instantiable class for GDNative support.

/*
A little extra info on the tracker ids, these are unique per tracker type so we get soem consistency in recognising our trackers, specifically controllers.
The first controller that is turned of will get ID 1, the second will get ID 2, etc.
The magic happens when one of the controllers is turned off, say controller 1 turns off, controller 2 will remain controller 2, controller 3 will remain controller 3.
If controller number 1 is turned on again it again gets ID 1 unless another new controller was turned on since.
The most likely scenario however is a controller that runs out of battery and another controller being used to replace it.
Because the controllers are often linked to physical objects, say you're holding a shield in controller 1, your left hand, and a gun in controller 2, your right hand, and controller 1 dies:
- using our tracker index would suddenly make the gun disappear and the shield jump into your right hand because controller 2 becomes controller 1.
- using this approach the shield disappears or is no longer tracked, but the gun stays firmly in your right hand because that is still controller 2, further more, if controller 1 is replaced the shield will return.

The ARVR server is a singleton object that gives access to the various
objects and SDKs that are available on the system.
Because there can be multiple SDKs active this is exposed as an array
and our ARVR server object acts as a pass through
Also each positioning tracker is accessible from here.
I've added some additional info into this header file that should move
into the documention, I will do so when we're close to accepting this PR
or as a separate PR once this has been merged into the master branch.

World scale allows you to specify a scale factor that is applied to all positioning vectors in our VR world in essence scaling up, or scaling down the world.
For stereoscopic rendering specifically this is very important to give an accurate sense of scale.
Add controllers into the mix and an accurate mapping of real world movement to percieved virtual movement becomes very important.
Most VR platforms, and our assumption, is that 1 unit in our virtual world equates to 1 meter in the real mode.
