// 04-10-2010  M. Kelsey -- Replace G4String keys with integers (ZZZAAA),
//                          move string operation to GenerateFilename()
// 17-11-2010 V. Ivanchenko - make as a classical singleton. 
//
// 17-10-2011 L. Desorgher -- Allow the user to replace the radioactive 
//               decay data provided in Geant4 by its own data file for 
//               a given isotope
// 06-01-2012 V. Ivanchenko - added nuclear level data structure for 
//               usage in HEP where internal conversion is neglected;
//               cleanup the code; new method GetLevelManager  
// 19-11-2014 M. Asai - protection against reading the same file from
//               more than one worker threads
