//
// 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.
