Class MP2R12Energy is the object that computes and maintains MP2-R12 energies.

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. This must be implemented by the derived class if the class has data.

Reimplemented from sc::SavableState.
