Detailed Description

also gives PseudoJet & JetDefinition

will allow a test for FJ3this is what we need from Pythia8 FASTJET_VERSION is only defined from version 3 onwards so we can use it to test that we have a sufficiently recent version place the code here inside the FJ namespace

A class derived from a pythia 8 particle and that also derives from PseudoJet::UserInfoBase, so that it can be used as UserInfo inside PseudoJets, but also be cast back to the Pythia8 particle
