18 Revision 2009/04/20 A. De Caro
19     - added two new global variables, called fTOFGeometry and fTOFdigits;
20     - added a new method, called FindClustersWithoutTOT,
21       to transform TOF digits with fTOT=0 in one pad clusters;
22     - update of the covariance matrix elements for the TOF clusters
