Modules
module	modulefft
	This module contains fast fourier transform wrappers. We use the convention of the FFT without any prefactor (just like FFTW), This implies that the inverse transform of the transform gives the original sequence times the number of gridpoints, i.e. FFT^+[FFT^-[x]]= N*[x].
Functions/Subroutines
subroutine	modulefft::get_FFT1D (instruction, length1, vec, INFO)
	This is the FFTW3 wrapper for the 1D fft.
subroutine	modulefft::get_FFT2D (instruction, length1, length2, vec, INFO)
	This is the FFTW3 wrapper for the 2D fft.
subroutine	modulefft::get_FFT3D (instruction, length1, length2, length3, vec, INFO)
	This is the FFTW3 wrapper for the 3D fft.
