/**
 * The AliHLTPHOSPeakfinder class is the class for extracting the basic signal parameters
 * "timing" and "energy" from the PHOS raw data. Physical data will for a given readout channel be
 * a sequense of ADC digitized 10 bit integer values, however for performance reasons all values used in
 * calculation is of type double.
