Bug for simExtAtracsysFusionTrackAddObject

[Chunting]

In robone.lua, there is a bug in function simExtAtracsysFusionTrackAddObject. This function serves to visulize the object in real-time based on tracker data.

The second function won't work, it seems that the parameter ObjectBeingMeasured, e.g. (Fiducial#22) can only appear once. This is a bug to fix.

simExtAtracsysFusionTrackAddObject('OpticalTrackerBase#0',  -- ObjectToMove
	 'Fiducial#22',               -- FrameInWhichToMoveObject
        'Fiducial#22',               -- ObjectBeingMeasured
	 '22'                             -- GeometryID
	)		

simExtAtracsysFusionTrackAddObject('Marker22',             -- ObjectToMove
	'OpticalTrackerBase#0',   -- FrameInWhichToMoveObject
	 'Fiducial#22',            -- ObjectBeingMeasured
	  '22'                      -- GeometryID
 )
