Used internally by the library to produce "real" log messages
in the log generated by the internal classes. If this class is not included in the
generated library, only codes will be printed.
Note that if the library is used in the AMD version then it may be necessary,
depending on the AMD implementation in use, to require this class to make the
"real" log messages appear in the log.
It is suggested not to import this class unless a client log is needed
for debugging purposes.
programmatically obtain a log message associated to a given log code
exploiting the LogMessages.getMessage method.
