class Tool from GeomLib
---Purpose: The methods of this class compute the parameter(s) of a given point on a
-- curve or a surface. The point must be located either
-- on the curve (surface) itself or relatively to the latter at
-- a distance less than the tolerance value.
-- Return FALSE if the point is beyond the tolerance
-- limit or if computation fails.
-- Max Tolerance value is currently limited to 1.e-4 for
-- geometrical curves and 1.e-3 for BSpline, Bezier and
-- other parametrical curves.

---Purpose:
-- Extracts the parameter of a 3D point lying on a 3D curve
-- or at a distance less than the tolerance value.
