Logger class allowing serial logging from multiple processes into a single log file.
To realize this, the MPHandler creates a thread listening for log messages, whereas the
emit method has been overwritten by a method sending the log message to the listening
thread. Therefore, only one process (the one hosting the listener thread) actually writes
into the log file.
