54/// \class AliMUONESDInterface
55///
56/// There are 2 way of using thid converter between MUON track/cluster/digit
57/// and ESDMuon track/cluster/pad:
58///
59/// 1) using the static methods converting the objects one by one
60///
b1fea02e 61/// 2) loading a whole ESDEvent and using the finders and/or the iterators
103e6575 62/// to access the corresponding MUON objects
63///
ad3c6eda 64/// note: You can set the recoParam used to refit the MUON track with ResetTracker(...);
65/// By default we use Kalman filter + Smoother
