Accidentally added the binary instead of the source to version control. Fixed that. These files were unchanged from the last commit, commit message duplicated here: Included fft result (from Mathematica) against which FftwTransform is tested and compared for both the forward and reverse transforms. Both makefiles were updated to actually clean the executable (only libraries were cleaned before, of which there are none anyway). Put in a preprocessor macro to use the init_ function instead of initialization lists because the constructors were getting ornery. When additional fftw transforms are written it will further code reduction.
