Use FFTW to speed up fourier transform #87

Closed PrometheusPi closed 7 years ago

This uses the FFTW3 library for fast FFT calculations. Since it is installed on our "home" cluster - the use and maintenance is easier. It is also (a bit) faster than other implementations tested. It is not yet the real FFT and data copying is still involved - thus it might even get faster with future code versions.

Also my diploma thesis is added as reference.
