/** \class PolyLineParametricPath
 * \brief  Represent a path of line segments through ND Space
 *
 * This class is intended to represent parametric paths through an image, where
 * the paths are composed of line segments.  Each line segment traverses one
 * unit of input.  A classic application of this class is the representation of
 * contours in 2D images, especially when the contours only need to be
 * approximately correct.  Another use of a path is to guide the movement of an
 * iterator through an image.
