18/// \class AliMUONLegacyClusterServer
19///
20/// Special implementation of AliMUONVClusterServer, which will only return
21/// clusters from a pre-defined cluster store.
22///
23/// Made to recover the old (i.e. before introduction of VClusterServer) behavior
24/// of the MUON recontruction where rec points were always written to TreeR,
25/// and then the tracking picked them from that tree, in order to have the
26/// possibility to save full rec points (for debugging the spectro, mainly, should
27/// not be an option used during final production).
