// Class description:
//
// An interface of an "importance store" used by importance sampling.
// It defines how a importance value together with a "cell" 
// (a G4VPhysicalVolume and a replica number) has to be added
// to the "importance store" and how a importance value can be derived 
// from the "importance store". 
//
