[Rivet] HepMC namespace reference

[Ivan Glushkov]

Dear experts,

could you point me to documentation about the HepMC namespace? I am especially interested in GenParticle, and the means to get the decay products of a given particle decay. I tried here (http://rivet.hepforge.org/code/dev/a00604.html), but it is empty..

	Cheers,
	Ivan
