added fingers base, palm velocity and hand openness (sphere radius,
sphere position).
added more gestures data:
key tap position;
screen tap position;
swipe velocity;
swipe duration in seconds and micros;
circle position;
removed binaries
Replaced ofBox(…) by non-deprecated ofDrawBox(…)
Looks like ofStyle does not cover lighting, added ofDisableLighting() call to deal with that.
Added a getter to see if the Leap controller is connected, and a setter to toggle receiving frames when the app is running in the background.
Updated status message. We don't need any Leap app to run before running this one anymore.
Fixed return type.
Added a pre-compiler check to make sure the addon still compiles on older oF versions.
