This PR includes two additional Python routines to do Fourier transforms and inverse Fourier transforms in SPEC formalism. Using numpy.fft package, we can indeed reconstruct the $\cos(m\theta-n\phi)$ and $\sin(m\theta-n\phi)$ Fourier series after some postprocessing.
I also started including unit tests - which should be extended to all Python routines eventually.
