Description:  The ellipse fitting routines available are:

              ELLIPSE1        Which finds the initial estimates of
                              the ellipse parameters.
              ELLIPSE2        Which finds the actual ellipse parameters
                              by a least-squares fit.
                              ELLIPSE1 can be used to determine the
                              initial estimates which are needed by
                              ELLIPSE2
