Add nodes that detect the types of gestures supported by the Leap Motion API:
CircleGesture A circular movement by a finger.
SwipeGesture A straight line movement by the hand with fingers extended.
ScreenTapGesture A forward tapping movement by a finger.
KeyTapGesture A downward tapping movement by a finger.
Currently, Vuo has limited support for gestures, being able to detect pinch and grab amount with the Get Hand Values node. Might be helpful to add gesture nodes for these, too, as is done in oz.LeapMotion for Quartz Composer.
