// Class G4VSamplerConfigurator
//
// Class description:
//
// This is an interface for configurators setting up processes
// needed for importance sampling and scoring. 
// The Configurator may be given a pointer to another Configurator.
// If a configurator will be given a pointer to another configurator
// it may obtain a G4VTrackTerminator from the given Configurator.
// This way it is possible to delegate the killing of a track.
