// Class description:
//
// This is the class which plays an essential role in tracking particles.
// It takes cares of all message passing between objects in the different
// categories (for example, geometry - including transportation, interactions
// in matter, etc). Its public method 'stepping' steers to step the particle.
// Only used within the Geant4 kernel.
