 Tool for profiling and testing the FFT libraries used in ABINIT.
 Allowed options are: 
   fourdp --> Test FFT transforms of density and potentials on the full box.
   fourwf --> Test FFT transforms of wavefunctions using the zero-pad algorithm.
   gw_fft --> Test the FFT transforms used in the GW code.
   all    --> Test all FFT routines.
