Detailed Description

Provides safe access to the TrackInformation part of a G4Track. If the G4Track pointer/reference is const, a const reference to the TrackInformation is returned, else a non-const reference is returned. The TrackInformationExtractor checks for the existance of TrackInformation and for the validity of the dynamic_cast; It will throw an excepton if it is not possible to return TrackInformation, but it will do it's best to satisfy the request (in some cases it may even create the TrackInformation on-the-fly).
