class AliCluster: public TObject

                         Class AliCluster
 This is the future base for managing the clusters in barrel detectors.
 It is fully interfaced with the ROOT geometrical modeller TGeo.
 Each cluster contains XYZ coordinates in the local tracking c.s. and
 the unique ID of the sensitive detector element which continas the
 cluster. The coordinates in global c.s. are computed using the interface
 to TGeo and will be not overwritten by the derived sub-detector cluster
 classes.

 can be used to force the calculation of the ideal
 matrix.

const TGeoHMatrix* GetTracking2LocalMatrix() const

 Get the matrix which is stored with the PN entries in TGeo.
