class PrefAndRec from AdvApprox inherits Cutting from AdvApprox

    ---Purpose : 
    -- inherits class Cutting; contains a list of preferential points (pi)i
    -- and a list of Recommended points used in cutting management.

    Create(RecomendedCut : Array1OfReal;

           Weight        : Real = 5 ) 
    returns PrefAndRec

    returns Boolean 
    ---Purpose: 
    --     cuting value is
    --    - the recommended point nerest of (a+b)/2 
    --      if pi is in ]a,b[ or else
    --   -  the preferential point nearest of (a+b) / 2
    --     if pi is in ](r*a+b)/(r+1) , (a+r*b)/(r+1)[ where r = Weight
    --   -  or (a+b)/2 else.
