//
// ClassName:   HistoManager
//
// Description: Singleton class to hold parameters and build histograms.
//              User cannot access to the constructor.
//              The pointer of the only existing object can be got via
//              HistoManager::GetPointer() static method.
//              The first invokation of this static method makes
//              the singleton object.
//
// Author:      V.Ivanchenko 27/09/00

// Modified:
// 04.06.2006 Adoptation of Hadr01 (V.Ivanchenko)
// 03.10.2006 Add csFlag (V.Ivanchenko)
// 16.11.2006 Add beamFlag (V.Ivanchenko)
