ntcFunctionCP2 is a class introduced to be able to sum two functions. Setting two functions f,g with the method SetAddends, its method EvaluateFunction returns the sum of the two functions. No homology method is defined for this function as there is no way to guess it from addends. This class has been introduced primarily to allow an easy implementation of methods like ntcPlaneFoliation::SetCriticalCurves where is needed to create a new function form the gradient of the Hamiltonian and the components of the 1-form.
