* HepMC/SimpleVector: remove FourVector::mag() and ThreeVector::mag()
Change test/testSimpleVector.cc and test/testMass.cc to reflect this.

* HepMC/HepMCDefs.h: New header containing HEPMC_HAS_UNITS and
similar macros so users can check for various code features.
HepMC/GenEvent.h includes HepMCDefs.h.
* HepMC/Version.h: Use new HEPMC_VERSION macro.

* HepMC/GenParticle: add is_undecayed(), has_decayed(), and is_beam_particle()
convenience methods. Test these methods in test/testHepMC.

2009-01-28 Lynn Garren

* remove HepMC/IO_Ascii.h and test/testDeprecated
