Message:

FunctionModel now uses list_of_arguments to split sequence of subsets of distances.

• this fixes ambiguities with the set of distances: Imagine the distances within a water molecule as OH (A) and HH (B). We then may have a sequence of argument_t as AABAAB. And with the current implementation of CompoundPotential::splitUpArgumentsByModels() we would always choose the latter (and more complex) model. Hence, we make two calls to TriplePotential_Angle, instead of calls twice to PairPotential_Harmonic for A, one to PairPotential_Harmonic for B, and once to TriplePotential_Angle for AAB.
• now, we new list looks like A,A,B,AAB where each tuple of distances can be uniquely associated with a specific potential.
• changed signatures of EmpiricalPotential::operator(), ::derivative(), ::parameter_derivative(). This involved changing all of the current specific potentials and CompoundPotential.
• TrainingData must discern between the InputVector_t (just all distances) and the FilteredInputVector_t (tuples of subsets of distances).
• FunctionApproximation now has list_of_arguments_t as parameter to evaluate() and evaluate_derivative().
• DOCU: docu change in TrainingData.
