FeatureSet with features being defined using a python script.
The python script should define a getNewFeaturesString function which has to output a vector of string features for the input token

Post-constructor.
The normal implementation should call simply inherited::build(), then this class's build_(). This method should be callable again at later times, after modifying some option fields to change the "architecture" of the object.
