Due to ARC error i removed the release stuff. Strange that this is part of the current master but older code on my computer had that already removed.
- use VNDetectFaceLandmarksRequest with revision = 2 which returns 68 points - draw lines on face features - draw bounding box - added info to readme

I also borrowed code from ofxFaceTracker2 to help with the indices to polyline drawing.
