//! 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.
//!
//! Construction of a BRepBlend_Line between a surface and
//! a pcurve on surface from an approached
//! starting solution. The output entries of this builder
//! are of the same nature as of the traditional walking
//! but the requirements on the Line are not the same
//! If the determination of validity range is always
//! guaranteed, the criteria of correct repartition of sections
//! before smoothing are not respected. The resulting Line
//! is f(t) oriented.
