 multiplication operator
 The operator can be used to 'combine'

 From detector name and module number (according to detector numbering)
 build fVolUID, unique numerical identity of that volume inside ALICE
 fVolUID is 16 bits, first 5 reserved for detID (32 possible values),
 remaining 11 for module ID inside det (2048 possible values).

 From the fVolUID, unique numerical identity of that volume inside ALICE,
 (voluid is 16 bits, first 5 reserved for layerID (32 possible values),
 remaining 11 for module ID inside det (2048 possible values)), sets
 the argument layerId to the identity of the layer to which that volume
 belongs and sets the argument modId to the identity of that volume
 internally to the layer.

 Return the geometry level of the alignable volume to which
 the alignment object is associated; this is the number of
 slashes in the corresponding volume path
