18//This class produces PHOS digits of one event

21// For example:
22// TClonesArray *digits = new TClonesArray("AliPHOSDigit",100);
23// AliRawReader* rawReader = new AliRawReaderDate("2006run2211.raw");
24// AliPHOSRawDecoder dc(rawReader);

26// AliPHOSRawDigiProducer producer;
27// producer.MakeDigits(digits,&dc);
