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