;;
;;  Title:  utl_distance.il
;;
;;  Purpose:  To find the distance between two point or
;;	      to find the distance from a given point to 0,0
;;
;;
;;  Example #1:
;;
;;		distance = utl_distance(pt1 pt2)
;;		pt1 = 35.0,50.0   pt2 = 65.0,90.0   distance = 50.0
;;
;;
;;  Example #2:
;;
;;		distance = utl_distanceAbsolute(pt)
;;		pt = 30.0,40.0   distance = 50.0
