/**

	The process of calibrating VRIK is fucking painful.
	
	Avatars of Note:
		TurtleNeck Ferret- close feet, far shoulders, nonideal rig.
		Space Robot Kyle- the worst bone rolls on the planet, tpose/headikcalibration fixed it mostly... ish.
		Exteratta- knees bend backwards without proper tpose.
        Chito- left foot is far back without proper tpose & foot ik distance, was uploaded in falling anim state.
        Atlas (portal2)- Wide stance, proper feet distance needed to be calculated.
        Freddy (gmod)- Doesn't have any fingers, wristToPalmAxis & palmToThumbAxis needed to be set manually.

	Most other avatars play just fine.
