50///
51/// There are 2 way of using thid converter between MUON track/cluster/digit
52/// and ESDMuon track/cluster/pad:
53///
54/// 1) using the static methods converting the objects one by one
55///
56/// 2) loading a whole ESDEvent and using the getters and/or the iterators
57/// to access the corresponding MUON objects
