This is a very simple example for using the multi-finger chord classifier

1. Perform the calibration first: 
	There are 3 families of multi-finger chords: three neighbouring fingers (hold all fingers down at the same time)
	thumb-pinky basis family starts always with thumb-pinky first (cyan coloured in the instruction) and then you hold down one of the three fingers. (two step posture)
	thumb-index basis family starts by holding down thumb and index (cyan coloured in the instruction) followed by the third finger. (two step posture)


2. go to the "Demo" tap and try out the postures. Touch events will be classified and the instruction of the detected posture will be shown.
