Fix FFT class to work on fftshifted data directly #45

Closed chaithyagr closed 5 years ago

chaithyagr commented 5 years ago

The FFT2 class works directly on fftshifted data. This causes a missmatch in the way NFFT / NUFFT and FFT2 class work. We need to fix this. This will have an impact on tests / generate_operators and also on examples. Thus creating a new issue for this
