    )
    
inherits FunctionSetWithDerivatives from math

      	---Purpose: This class is the template function for the intersection
      	--          between a curve and a surface.
      	--          It is possible to implement such a function with an
      	--          instantiation of :
      	--           - ZerCSParFunc for the intersection between a 3d curve
      	--             and a surface.
      	--           - ZerCOnSSParFunc for the intersection between a curve
      	--             on surface and another surface.
