//      2)  LOGFILE_ASSERTIONS                                              use it to define the file name to log assertions if LOGTYPE=LOGTYPE_FILE...
//      3)  LOGFILE_WARNINGS                                                use it to define the file name to log warnings if LOGTYPE=LOGTYPE_FILE...
//
//      active for "non product":
//
//      4)  LOG_ASSERT( BCONDITION, STEXT )                                 assert some critical errors wich depend from given condition
//      4a) LOG_ASSERT2( BCONDITION, SMETHOD, STEXT )                       same like 4) + additional location of error
//      5)  LOG_ERROR( SMETHOD, STEXT )                                     show errors without any condition
//
//      active for debug only!
//
//      6)  LOG_EXCEPTION( SMETHOD, SOWNMESSAGE, SEXCEPTIONMESSAGE )        show/log an exception for easier debug
//      7)  LOG_WARNING( SMETHOD, STEXT )                                   should be used to detect leaks in algorithm, mechanism or operation handling
