Detailed Description

Module to analyze the particle listing as provided by common event generators.

Module to analyze the particle listing as provided by common event generators equivalent to PYLIST(1) (from pythia). It is expected to run on vectors of reo::GenParticles. For an example of use have a look to:

PhysicsTools/HepMCCandAlgos/test/testParticleTreeDrawer.py

Caveats: Status 3 particles can have daughters both with status 2 and 3. In pythia this is not the same mother-daughter. The relations are correct but special care has to be taken when looking at mother-daughter relation which involve status 2 and 3 particles.
