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