// Different signal extractors can be set with the command SetExtractor()
// Only extractors deriving from MExtractor can be set, default is MExtractSlidingWindow
//
// Different arrival time extractors can be set with the command SetTimeExtractor()
// Only extractors deriving from MExtractTime can be set, default is MExtractTimeHighestIntegral
//
// At the end of the eventloop, plots and results are displayed, depending on 
// the flags set (see DisplayResult()) 
// 
// If the flag SetFullDisplay() is set, all MHCameras will be displayed. 
// if the flag SetDataCheckDisplay() is set, only the most important ones are displayed 
// Otherwise, (default: SetNormalDisplay()), a good selection of plots is given
//
// The absolute light calibration devices Blind Pixel and PIN Diode can be switched on
// and off with the commands:
//
// - SetUseBlindPixel(Bool_t )
// - SetUsePINDiode(Bool_t )
