12!> 05.2002 moved from qs_scf (see there the history) [fawzi]
13!> JGH [30.08.02] multi-grid arrays independent from density and potential
14!> 10.2002 introduced pools, uses updated rho as input,
15!> removed most temporary variables, renamed may vars,
16!> began conversion to LSD [fawzi]
17!> 10.2004 moved calculate_w_matrix here [Joost VandeVondele]
