Log Message:
-----------
Added a new "NONE" log level that goes beyond the current MINIMUM level (0) and
does not even try to open a log file. This mode should be used in applications
that will be running in a multithreaded environment, to avoid collisions over
the (static) LogService between the different instances of the Learning PR.
Also allow verbosity level to be specified in words (NONE, MINIMUM, NORMAL or
DEBUG) instead of numbers (-1, 0, 1 or 2).
