// Description:
// This class is the CDBPreProcessor interface,
// supposed to be implemented by any detector
// interested in immediate processing of data 
// which is retrieved from DCS.
// For every particular run set of aliases and
// their corespoding value sets are returned.
// Usage schema:
//	1) virtual void Initialize(Int_t run, UInt_t startTime, UInt_t endTime)	
//	This method is called at the begining of data retrieval.
//	run: run number
//	startTime: when the run started
//	endTime: when the run finished	
//
//	2) virtual void Process(const char* alias, TObjArray& valueSet,
//                       Bool_t hasError)	
//	
//	This method is called for every particular alias which the detector
//	is registered in the configuration (see AliShuttleConfig).
//	alias: alias name
//	valueSet: collection of AliDCSValue
//	hasError: flag indicating if some error has happened during
//		the retrieaval of the data for this alias.
//
//	3) virtual void Finalize()
//	This method is called after the last alias has been processed.
