/* Classe che consente la manipolazione dei nomi di files
 * e delle estensioni.
 * Uso consigliato:
 * derivare una classe da questa, aggiungendo funzioni
 * che generino direttamente i nomi del file con l'estensione desiderata
 * Ad esempio:


 class MyFile : public FileName {
  public:
    MyFile(char* sFName) : FileName(sFName) { 
       NULL 
    };
    
    char* sOldFile(void) { 
       return _sPutExt(NULL); 
    };
    
    char* sDatFile(void) { 
       return _sPutExt(".dat"); 
    };
 };
