/// \brief The macro for testing the shuttle preprocessors 
///
/// This macro runs the test preprocessor for MUON.
/// It uses AliTestShuttle to simulate a full Shuttle process
///
/// The input data has to be created first by other processes (or is created
/// here by CreateDCSAliasMap() for tracker HV).
///
/// To play with it, you'll have to set/modify several lines, to
/// - a) select input files, using shuttle->AddInputFile()
/// - b) select run type, using shuttle->AddInputRunParameter() (the run type
///      dictates which task is really performed by the MUONPreprocessor
///
/// You must load relevant libraries (besides normal MUON ones) before
/// compiling this macro :
/// <pre>
/// gSystem->Load("$ALICE_ROOT/SHUTTLE/TestShuttle/libTestShuttle");
/// gSystem->Load("libMUONshuttle.so");
/// </pre>
///
/// For more information on usage, please see the \ref README_shuttle page.
