object FFT
The FFT object provides a method to transform a signal in the time domain
(e.g., a times series) in its representation in the frequency domain.
The inverse transform is also provided.

Transform a signal in the time domain into its representation in the frequency domain using the Cooley–Tukey Fast Fourier Transform algorithm.
Transform a signal in the time domain into its representation in the frequency domain using the Cooley–Tukey Fast Fourier Transform algorithm. The values are updated in place. FIX - algorithm should allow signals of any size
- x
