 * @class AliHLTTPCCalibSignalComponent

 * This class is the component for the AliTPCCalibSignal class used for 
 * pedestal calibration of the TPC. It uses the high-level interface and
 * the output is the TObject of AliTPCCalibSignal.
 *
 * The component has the following component arguments:
 * -    The RCU format:  rcuformat  
 *      which can be either 
 *        - old ( used in the TPC Commissioning )
 *        - new
