Merged COOP/COHP functionality Merged the COOP/COHP/PDOS code from the 2.1 branch complex.
��-- Functionality changes:
* The wavefunction file is now in WFSX format (well-packed, single-precision, and thus significantly smaller). The Util/wfsx2wfs program can be used to re-generate the old format.
* The xijo array (for relative positions between interacting orbitals) is always produced.
-- New features:
Option COOP.Write triggers the creation of a wavefunction file (for the SCF-k-point set) and an HSX file (enhanced HS format) that can later be processed by Util/COOP/mprop for the off-line generation of COOP/COHP/(P)DOS.
