ISPOINTONPOLYLINE Test if a point belongs to a polyline.

   B = isPointOnPolyline(POINT, POLY)
   Returns TRUE of the point POINT belong to the polyline defined by the
   set of points in POLY.

   B = isPointOnPolyline(POINT, POLY, TOL)
   Specify the absolute tolerance for testing the distance between the
   point and the polyline.

   Example
       pt1 = [30 20];
       pt2 = [30 10];
       poly = [10 10;50 10;50 50;10 50];
       isPointOnPolyline([pt1;pt2], poly)
       ans =
            0
            1
