LogHandler is responsible for causing some side-effect with a LogRecord. This usually includes formatting the record
with a Formatter and writing it to a Writer, although some more creative implementations exist to do more advanced
actions. LogHandlers are added to Logger instances via withHandler, although it's usually sufficient to use the
withHandler method that takes a Formatter and Writer instead of defining a LogHandler manually.
