///
/// The macro uses the 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.
///
/// By 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.
