+Revision 1.20.1 2007/05/19 decaro
+ Added the following methods:
+ GetVolumeIndices(Int_t index, Int_t *det), to get
+ the volume indices (sector, plate, strip, padz, padx,
+ stored respectively in det[0], det[1], det[2], det[3], det[4])
+ from the calibration channel index;
+ NStrip(Int_t nPlate), to get the strips number
+ per each kind of TOF module.
