This solves issue #55 because the sort_ci0 step uses a different objective function than the VRVSolver to sort the states. Even though LASSIS uses a state-averaged approach, the identity of the ground state matters because the H(E)|0>=E|0> equation can only be solved for the ground state, so swapping them willy-nilly prevents the solver from ever converging.
