class SurfRstLineBuilder from BRepBlend
---Purpose: This class processes data resulting from
-- Blend_CSWalking taking in consideration the Surface
-- supporting the curve to detect the breakpoint.
--
-- The criteria of distribution of points on the line are detailed
-- because it is to be used in the calculatuon of values approached
-- by an approximation of functions continued basing on
-- Blend_SurfRstFunction.
--
-- Thus this pseudo path necessitates 3 criteria of regrouping :
--
-- 1) exit of the domain of the curve
--
-- 2) exit of the domain of the surface
--
-- 3) stall as there is a solution to the problem
-- surf/surf within the domain of the surface
-- of support of the restriction.
