// Macro MUONrecoNtuple.C (TO BE COMPILED)
// for testing the C++ reconstruction code
// and producing an Ntuple with reconstructed tracks
// in output file "MUONtrackReco.root".
// An example for using the Ntuple is in the macro MUONmassPlot.C

// Arguments:
//   FirstEvent (default 0)
//   LastEvent (default 0)
//   RecGeantHits (1 to reconstruct GEANT hits) (default 0)
//   FileName (for signal) (default "galice.root")
//   BkgGeantFileName (for background),
//      needed only if RecGeantHits = 1 and background to be added

// IMPORTANT NOTICE FOR USERS:
// under "root" or "root.exe", execute the following commands:
// 1. "gSystem->SetIncludePath("-I$ALICE_ROOT/MUON -I$ALICE_ROOT/STEER -I$ROOTSYS/include")" to get the right path at compilation time
// 2. ".x loadlibs.C" to load the shared libraries
// 3. ".x MUONrecoNtuple.C+()" with the right arguments, without forgetting the "+" which implies the compilation of the macro before its execution
