/** Logger class allows recording of tagged messages.
 *<p>A program using Logger would perform the following steps:
 *	-# Define a Logger object stating the fileName of the logging file, or using the default stderr.
 *	-# State the desired log level. Can be SEVERE, WARNING, INFO, CONFIG, FINE, FINER or FINEST.
		If the log level is not explicitly stated, the default level is INFO.
 *	-# Log any message that would be necessary using the method corresponding to the desired log level of the message.
 *		Only those messages having level from SEVERE to the current level stated are recorded in the log file.
