    Description copied from class: PotentialMolecular
    
    Informs the potential of the box on which it acts. Typically this requires at least that it update the nearestImageTransformer of its coordinatePair (if it uses one), e.g.: cPair.setNearestImageTransformer(box.boundary());

public double energy(IMoleculeList pair)
```
    Description copied from class: PotentialMolecular
    
    Returns the interaction energy between the given molecules. There might be 0, 1, 2 or more atoms in the IMoleculeList.
