/**
 * @class AliHLTCaloRawAnalyzerComponentv3
 * This the new and fast version of the component taking care of the decoding and energy and timing 
 * extraction of the raw data from PHOS.
 *
 * <h2>General properties:</h2>
 *
 * Component ID: \b PhosRawAnalyzerv3 <br>
 * Library: \b libAliHLTCalo.so     <br>
 * Input Data Types: @ref <br>
 * Output Data Types: @ref AliHLTCaloDefinitions::fgkChannelDataType<br>
 *
 * <h2>Mandatory arguments:</h2>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
 * \li No mandatory arguments for component                           <br>
 *
 * <h2>Optional arguments:</h2>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
 * \li -offset      <i> value </i> <br>
 *      gives the offset added to the data during zero suppression (default value: 0)
 * \li -bunchsizecut <i> value </i> <br>
 *      minimum number of samples a bunch must contain to be considered  (default value: 0)
 * \li -minpeakposition <i> value </i> <br>
 *      cut on minimum postion of the peak in the bunch (defaul value: 0)
 * \li -maxpeakposition <i> value </i> <br>
 *      cut on maximum postion of the peak in the bunch (defaul value: 100)
 *
 * <h2>Configuration:</h2>
 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
 * \li No configuration arguments 
 *
 * <h2>Default CDB entries:</h2>
 * \li No CDB entry yet, will come.
 *
 * <h2>Performance:</h2>
 * Pretty good (~ 3 kHz), depends on amount of data...
 *
 * <h2>Memory consumption:</h2>
 * Depends on the amount of data, but pretty godd
 *
 * <h2>Output size:</h2>
 * Depends on the amount of data...
 *
 * More detailed description. (Soon)
