   7 package Extrema
   8     ---Purpose: This package calculates the distances between
   9     --          points, curves and surfaces.
  10     --          In general case, the algorithm to find the
  11     --          distances is a minimization algorithm of a function
  12     --          of variables: F(X). It is stopped when:
  13     --            for X1=X+Dx, F(X) and F(X1) are the same.
  14     --          The value of Dx can be calculated for all the
  15     --          algorithms.
  16
  17     ---Level : Public.
  18     --  All methods of all  classes will be public.
