Beat Histogram

A feature extractor that extracts the Beat Histogram from a signal. This is histogram showing the strength of different rhythmic periodicities in a signal.

This is calculated by taking the RMS of 256 windows and then taking the FFT of the result.

IMPORTANT: The window size of 256 RMS windows used here is hard-coded into the class BeatHistogramLabels. Any changes to the window size in this class must be made there as well.
