docs: Returns the information on the symmetry of the Hamiltonian
          describing the exchange energy of the system, taking into
          account relative direction of magnetic moments but not their
          absolute direction.
  
          This is not strictly accurate (e.g. some/many atoms will
          have zero magnetic moments), but defining symmetry this
          way is a useful way of keeping track of distinct magnetic
          orderings within pymatgen.
