 ListType CEXTREMES( CurveType Crv, NumericType Epsilon, NumericType Axis )

Computes the extreme set of the given Crv in the given axis (1 for X,
2 for Y, 3 for Z). Since this computation is numeric, an Epsilon is
also required to specify the desired tolerance. It returns a list of
all the parameter values (NumericType) in which the curve takes an extreme
value.

Example:

    extremes = CEXTREMES( Crv, 0.0001, 1 );

Computes the extreme set of curve crv, in the X axis, with
error tolerance of 0.0001. See also CZERO.
