+	Modifications (last one on top):

+		20110322 - WVR: Somehow the video-widget of faceAPI version 3.2.6. does not

+					    work with FaceTrackNoIR (Qt issue?!). To be able to use 

+						release 3.2.6 of faceAPI anyway, this console-app is used.

+						It exchanges data with FaceTrackNoIR via shared-memory...
