// This class is the main manager for AliShuttle. 
// It organizes the data retrieval from DCS and call the 
// interface methods of AliPreprocessor.
// For every detector in AliShuttleConfgi (see AliShuttleConfig),
// data for its set of aliases is retrieved. If there is registered
// AliPreprocessor for this detector then it will be used
// accroding to the schema (see AliPreprocessor).
// If there isn't registered AliPreprocessor than the retrieved
// data is stored automatically to the undelying AliCDBStorage.
// For detSpec is used the alias name.
