// Base macro for submitting single muon analysis.
//
// In case it is not run with full aliroot, it needs to have in the working directory:
//  - STEERBase.par
//  - AOD.par
//  - ESD.par
//  - ANALYSIS.par
//  - ANALYSISalice.par
//  - PWG3muon.par
//
// The macro reads ESDs and outputs file:
// - SingleMuESD.root
