// Class SpectralPeak: Processing Data class to store spectral peak data
///////////////////////////////////////////////////////////////////////////////
// Description:
// This class holds a basic data structure used for spectral processing: the
// the Spectral Peak. A Spectral Peak holds information about a particular
// spectral sample extracted from a Peak Detection Algorithm. Some information
// such as Frequency and Amplitude is mandatory, other as Phase and BinWidth
// may be needed for some particular applications and BinPos may be redundant
// with Frequency but is kept for backwards compatibility.
