 * Output to the log file, writing to the text file

//@config: Debug
 
// Logging is important part of debugging. First, you need to specify where the logging will be performed
// Generally, coat::logger may be use for the regular text-file output, not just for logging.
// In this case you may declare the coat::logger object within any function, output there and then call close()
coat::logger dbg("mylog.txt");
