 *
 * The design of the StParticleDefinition class and all concrete
 * classes derived from it is largely based on the design of the 
 * G4ParticleDefinition class from Geant4 (RD44).
 * Although the code is in large parts different (modified or rewritten)
 * and adapted to the STAR framework the basic idea stays the same.
