Carfac C++ revision 3, indluding more style improvements. The output structs are now classes again, and have separate storage methods for each output structure along with flags in the Run and RunSegment methods to allow for only storing NAPs if desired.

// Class: CARFACOutput
// *****************************************************************************
// The CARFACOutput object stores an array of EarOuput objects. It is meant as a
// container for the output generated by the CARFAC object's 'Run' and
// 'RunSegment' methods. Depending on the number of audio channels in the  input
// data, the CARFACOutput will have 1 or more EarOutput obects, each of which
// contains a set of two dimensional float arrays (FloatArray2d) representing
// the neural activation patterns (NAPs) generated by the CARFAC model.
//
// The 'InitOutput' method is used to initialize the arrays in each of the
// EarOutput sub-objects once the target data dimensions ears (n_ears), channels
// (n_ch) and timepoints (n_tp) are known.
//
// The 'MergeOutput' method is for integrating a smaller CARFACOutput into a
// larger CARFACOutput object. This is intended to be used in the context of
// the CARFAC class's 'Run' and 'RunSegments' methods.
