Message:

Extended FunctionModel by getFragmentSpecificExtractor() definition.

• shifted extractor_t from TrainingData to FunctionModel.
• implemented function for every specific potential.
• this is preparatory for generalizing function approximation in LevMartester.
• we make use of the newly introduced extractors in the potentials and the required number of charges is ASSERT'd.
