merge stuff from OLD_HYBRIDS and hybrids
New (not finished) version of hybrids
Minor modifications in HF part: convergence criterium is exnl
small bug fix in hybrid
small bug fix
ZORA is implemented on MT surface and in IR.
Koelling-Harmon for atoms implemented.
The radial solver for KH was apparently missing...
Linearized Koelling-Harmon for atoms.
Total energy is consistent with the main branch now.
first version of Raman code
Option to calculate the kinetic energy as (nabla a)*(nabla b) instead of a*(delta b) + (surface_terms) is added.
Linearized Koelling-Harmon without the small component is implemented.
some changes for molecules
Small component can be added now in (linearised) Koelling-Harmon calculations of atoms.
hmlaan is kind of rewritten. Should be faster now.
More hml* and olp* subroutines are tuned.
Angular integration is moved from hmlalon to hmlrad.
The small content of hmlaan, hmlalon, olpaan and olpalon is moved hamiltonandoverlapsetup.
small bug fix in mpi
