subroutine CORLSD(RS, ZTA, EC, VCUP, VCDN, ECRS, ECZTA, ALFC)
Uniform-gas correlation of perdew and wang 1991
input: seitz radius (rs), relative spin polarization (zta) output: correlation energy per electron (ec), up- and down-spin potentials (vcup,vcdn), derivatives of ec wrt rs (ecrs) &zta (eczta). output: correlation contribution (alfc) to the spin stiffness
