// ClassName:   hTestHisto
//  
// Description: Singleton class to hold Emc geometry parameters.
//              User cannot access to the constructor. 
//              The pointer of the only existing object can be got via 
//              hTestHisto::GetPointer() static method. 
//              The first invokation of this static method makes 
//              the singleton object.
