//--------------------------------------------------------------------------
// Macro for QA monitoring.
//
// In case it is not run with full aliroot, it needs the following libraries to compile:
//  - libSTEERBase
//  - libESD
//  - libAOD
//  - libANALYSIS
//  - libANALYSISalice
//  - libCORRFW
//  - libPWGmuon
//
// TString includePath = "-I${ALICE_ROOT}/PWGmuon ";  gSystem->SetIncludePath(includePath.Data());
//
// The macro reads results of the QA task and produce monitoring plots.
//
// Authors: Cynthia Hadjidakis - IPN Orsay
// QA histos from counters (event, track) and run per run histos
// To be done:
// - reorganize last part (reading and extracting info from run per run histos)
// - remove trigger selection when muon QA task modified (now a selection is done one triggers' name)
