* The ConstantQFolder takes a ConstantQ transform and folds its bins

* \b Parameters:
* - nConstantQBins: The number of bins on the Constant Q transform.
* - binsPerOctave: The number of bins that corresponds to each octave.
* \b Inputs:
* - A constant Q transform as a vector containing the real and imaginary pairs
* bins, so it is size nConstantQBins * 2
* \b Outputs:
* - A chromogram of binsPerOctave bins.
* @todo Only nConstantQBins that are multiple of binsPerOctave have been tested.
