11/// \brief Compact information for the muon generated tracks
12///
13/// Compact information for the muon generated tracks in the MUON arm
14/// useful at the last stage of the analysis chain
15/// provides a link between the reconstructed track and the generated particle
16/// stores kinematical information at gen. and rec. level and
17/// the decay history of the muon, allowing the identification of the
18/// mother process
19///
20/// To be used together with AliMUONPairLight
