1) Adding class AliAnalysisMuonUtility which contains static methods allowing to process AOD and ESD (muon) tracks in the same way. Using this class, there is no more need for the user to adapt his/her analysis code to run on AODs or ESDs. 2) Adding AliMuonEventCuts to handle cuts on event (e.g on fired trigger and SPD vertex). It also provides a way to select trigger classes based on their name (useful to fill information on many muon trigger classes at the same time). (Diego)
