These FFT convenience wrappers are intended to provide a few basic generic fft routines on our various platforms. As libraries and/or system change we should only have to update these wrappers, without having to modify each source program that needs to do fft's. Each program utilizing these routines should include the appropriate header file.

#include "fft.h"		Use with fixed-format sources.
#include "f90fft.h"		Use with free-format sources.
use dds		A module with most of DDS defined. Module interfaces for FFT wrappers limit data buffer types.
