   Public Member Functions
       MOPairIter (const Ref< MOIndexSpace > &space_i, const Ref< MOIndexSpace > &space_j)
           Initialize an iterator for the given MO spaces.
       virtual void start (const int first_ij=0)=0
           Start the iteration.
       virtual void next ()=0
           Move to the next pair.
       virtual operator int () const =0
           Returns nonzero if the iterator currently hold valid data.
       int ni () const
           Returns the number of functions in space i.
       int nj () const
           Returns the number of functions in space j.
       int i () const
           Returns index i.
       int j () const
           Returns index j.
       int nij () const
           Returns the number of pair combinations for this iterator.
       int ij () const
           Returns the current iteration.
