Message:

EmpiricalPotential and FunctionModel are now inherited virtually, have overlapping function definitions.

• EmpiricalPotential and FunctionModel differ only in the way of the derivative. The simple function evaluation is the same. EmpiricalPotential however desires the derivative with respect to the arguments, while FunctionModel requires the derivative with respect to the parameters.
• therefore, we shifted some of the function definitions in between the two and had to some typedefs in PairPotential_Harmonic and ManyBodyPotential_Tersoff to clarify ambiguities.
