// Remarks:         The concept of detector sets was initially proposed

// Description:
//
// This file contains the declaration of the classes HDetSet, HDetSetOut,
// HShowerDetSet, HMdcDetSet, HRichDetSet, HTofDetSet.
// These classes provide all functions to maintain the online objects of 
// the type "detector set".
