   This is a very simple filter based on logger name matching.

   <b>AcceptOnMatch</b>. If there is an exact match between the value
   of the <b>LoggerToMatch</b> option and the logger of the {@link
                spi::LoggingEvent LoggingEvent}, then the #decide method returns  {@link
                spi::Filter#ACCEPT ACCEPT} in case the <b>AcceptOnMatch</b> option value is set
   to <code>true</code>, if it is <code>false</code> then {@link
   spi::Filter#DENY} is returned. If there is no match, {@link
   spi::Filter#NEUTRAL} is returned.  A loggerToMatch of "root"
   matches both the root logger and a logger named "root".
