// Class for generating file names and paths.
// The input files:
// Config.C    - the basic AliRoot configuration file (Root macro)
//               When detector setup is defined interactively,
//               the alternative Config.C files per detector
//               are used.
// Config.in   - G4 specific configuration macros per detector
// The output files:
// g3calls.dat - the ASCII file with G3 geometry calls;
//               generation is switch on with /aliDet/writeGeometry command
//               in PreInit phase
// DetvN.xml   - XML geometry description file;                
//               generation is switch on with /aliDet/generateXML command
//               in Init phase
