9 : !> \brief Calculate the plane wave density by collocating the primitive Gaussian
10 : !> functions (pgf).
11 : !> \par History
12 : !> - rewrote collocate for increased accuracy and speed
13 : !> - introduced the PGI hack for increased speed with that compiler
14 : !> (22.02.02)
15 : !> - Added Multiple Grid feature
16 : !> - new way to get over the grid (01.03.02)
17 : !> - removed timing calls since they were getting expensive
18 : !> - Updated with the new QS data structures (09.04.02,MK)
19 : !> - introduction of the real space grid type ( prelim. version JVdV 05.02)
20 : !> - parallel FFT (JGH 22.05.02)
21 : !> - multigrid arrays independent from density (JGH 30.08.02)
22 : !> - old density stored in g space (JGH 30.08.02)
23 : !> - distributed real space code (JGH 17.07.03)
24 : !> - refactoring and new loop ordering (JGH 23.11.03)
25 : !> - OpenMP parallelization (JGH 03.12.03)
26 : !> - Modified to compute tau (Joost 12.03)
27 : !> - removed the incremental density rebuild (Joost 01.04)
28 : !> - introduced realspace multigridding (Joost 02.04)
29 : !> - introduced map_consistent (Joost 02.04)
30 : !> - Addition of the subroutine calculate_atomic_charge_density (TdK, 08.05)
31 : !> - rewrite of the collocate/integrate kernels (Joost VandeVondele, 03.07)
32 : !> - Extended by the derivatives for DFPT [Sandra Luber, Edward Ditler, 2021]
