//
// This is a COM wrapper for the OpenCV CamShift tracker.
// It implements ITracker so that CamShift can be used by the 3d Tracker filter.
// This is intended as sample code only.
// A complete implementation would have additional methods (in ICamShiftTracker)
// to control the CamShift tracker.
