// Class AliAttrib
// Generic handling of detector signal (calibration) attributes.
// Normally this class is only used as a base class to provide the various
// attributes to the derived class. An example of this is AliSignal.
// However, one can of course also use this class on its own as shown
// in the simple example hereafter.
//
// Example :
// ---------
// AliAttrib a;
// a.SetSlotName("PMT amplitude in Volt");
// a.SetGain(250.7);
// a.SetSlotName("Time of flight in ns",2);
// a.SetOffset(-22.5,2);
// a.SetSlotName("PMT amplitude in ADC",3);
// a.SetGain(1340,3);
// a.SetSlotName("TDC",4);
// a.SetOffset(10.75,"TDC");
// a.SetEdgeOn(3);
// a.SetDead(1);
// a.List();
