Detailed Description

A class implementing a logging system.

Messages are sent to the log system. If the importance (level) of a message is lower or equal to a given threshold, the message is printed. Otherwise, it is ignored.

Message printing is managed by log_stream classes. The logger_system can contain several log_stream. None checking is done when adding a log_stream to see if it is already in the system.
