// Macro for MUON alignment using physics tracks. The macro uses AliMUONAlignment
// class to calculate the alignment parameters.
// An array for the alignment parameters is created and can be filled with
// initial values that will be used as starting values by the alignment
// algorithm.
// Ny default the macro run over galice.root in the working directory. If a file list
// of galice.root is provided as third argument the macro will run over all files.
// The macro loop over the files, events and tracks. For each track
// AliMUONAlignment::ProcessTrack(AliMUONTrack * track) and then
// AliMUONAlignment::LocalFit(Int_t iTrack, Double_t *lTrackParam, Int_t
// lSingleFit) are called. After all tracks have been procesed and fitted
// AliMUONAlignment::GlobalFit(Double_t *parameters,Double_t *errors,Double_t *pulls)
// is called. The array parameters contains the obatained misalignement parameters.
// A realigned geometry is generated in a local CDB.
