#FFT Features
##Description The FFTFeatures class computes a number of features from an FFT signal. These features can include:
- the frequency bin that contains the frequency with maximum magnitude value
- the ratio between the maximum magnitude and the sum of all the magnitude values *the centroid of the FFT magnitude values *the top N frequency values
The FFT class is part of the Feature Extraction Modules.
