Sum-rule

Suggested by Hess and Iafrate, shown by Mori-A-1989, then generalised by Register-1992.

Beware -- an orthonormal set of phonon mode functions (in eg displacement u or polarization P) does _not_ imply an orthonormal set of potentials -- it is the potentials that appear in the form factors.
