/**
 * StandardLogHandler is a LogHandler implementation that uses a LogFormatter
 * class to serialize the LogMessage into a string, and then gives it to a
 * LogWriter object.
 *
 * This basically is a simple glue class that helps chain together
 * configurable LogFormatter and LogWriter objects.
 *
 * StandardLogHandler also supports ignoring messages less than a specific
 * LogLevel.  By default it processes all messages.
