// The AliDAQ class is responsible for handling all the information about   //
// Data Acquisition configuration. It defines the detector indexing,        //
// the number of DDLs and LDCs per detector.                                //
// The number of LDCs per detector is used only in the simulation in order  //
// to define the configuration of the dateStream application. Therefore the //
// numbers in the corresponding array can be changed without affecting the  //
// rest of the aliroot code.                                                //
// The equipment ID (DDL ID) is an integer (32-bit) number defined as:      //
// Equipment ID = (detectorID << 8) + DDLIndex                              //
// where the detectorID is given by fgkDetectorName array and DDLIndex is   //
// the index of the corresponding DDL inside the detector partition.        //
// Due to DAQ/HLT limitations, the ddl indexes should be consequtive, or    //
// at least without big gaps in between.                                    //
// The sub-detector code use only this class in the simulation and reading  //
// of the raw data.                                                         //
//                                                                          //
