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.
