// Class AliMUONGeometrySVMap
// ------------------------------------ 
// As the detection element frame is different from the
// frame of the sensitive volume(s) defined in Geant,
// the sensitive volumes have to be mapped to the detection 
// elements. In the map, fSVMap, the sensitive voolumes are specified
// by the full path in the volume hierarchy, defined as:
//  /volname.copyNo/volName.copyNo1/...
//
// The array of global positions of sensitive volumes fSVPositions
// is included to make easier the verification of the assignements 
// in the fSVMap.
