WrappedParamGenFunction class to wrap any multi-dimensional function implementing the operator()(const double * ) in an interface-like IParamFunction, by fixing some of the variables and define them as parameters.
i.e. transform any multi-dim function in a parametric function

Constructor as before but taking now a non - const pointer to a callable object.
This constructor is needed in the case FuncPtr is a std::unique_ptr which has a copy ctor taking non const objects
