  //!
  //! Warning:
  //! the Func should be valid reference to object of type
  //! inherited from class EvaluatorFunction from Approx
  //! with life time longer than that of the approximator tool;
  //!
  //! the result should be formatted in the following way :
  //! <--Num1DSS--> <--2 * Num2DSS--> <--3 * Num3DSS-->
  //! R[0] ....     R[Num1DSS].....                   R[Dimension-1]
  //!
  //! the order in which each Subspace appears should be consistent
  //! with the tolerances given in the create function and the
  //! results will be given in that order as well that is :
  //! Curve2d(n)  will correspond to the nth entry
  //! described by Num2DSS, Curve(n) will correspond to
  //! the nth entry described by Num3DSS
  //! The same type of schema applies to the Poles1d, Poles2d and
  //! Poles.
