update feature matrix, introduce macros for method names
2dp-P2NFFT with triclinic box shape in periodic dimensions
remove debug output
add triclinic test case for debugging
clean up triclinic test cases
include padding of r2c inputs in oversampling
fix build
remove padding of r2c inputs from interface and testcases
update manual
fix 3dto2d remap for r2c without padding
update PNFFT due to changes in PFFT interface
PFFT: implemented fftshift feature
P2NFFT: make use of FCS_PFFT macro
PFFT shift works for non-pruned FFTs
P2NFFT: turn on use of PFFT shift for precomputation
PNFFT: use PFFT shift
PNFFT: remove PNFFT_TEST_PFFT_SHIFT macro
PNFFT: always use internal local_size function
PFFT: bugfix fftshift
PFFT: bugfix r2c padding
