SpatialMOPairIter_eq gives the ordering of same-spin and different-spin orbital pairs if both orbitals of
       the pairs are from the same space.

       It iterates over all i >= j combinations (total of (ni_+1)*(ni_+2)/2 pairs).

intsc::SpatialMOPairIter_eq::ij_aa()const[inline],[virtual]
       Returns compound index ij for alpha-alpha case. The i == j combination doesn't make sense, so ij_aa()
       will return -1 for such pairs.

       Implements sc::SpatialMOPairIter.
