To save memory not anylonger the full path of a volume is stored in each hit but an encrypted form of it (f.e. /1_1/34_2/101_1/). The first number is the volumeID comming from the GeoManager and the second number is the copy number. This class helps you converting the encrypted ID into the path information and vice versa. It needs the informations of the GeoManager. Therefore one has to ensure that either an initialized TGeoManager pointer is given in the constructor with the correct goemetry or a filename with the correct geoemetry ("FAIRGeom")
