//! The properties stored in this class are the following:
//! - area of the contour,
//! - perimeter of the contour,
//! - ratio of average length to average width of the contour,
//! - average width of contour,
//! - notches (narrow 'V'-like sub-contours) on the contour and
//! their maximum width.
