specifies a service which formats log records for RFC4180-style CSV-Files
Every log record, as passed to XCsvLogFormatter::format,
will be formatted into a single row for a CSV file.
The sequence number, the thread ID, the time of the logged event,
the source class/method name will get logged alongside the message, if this
is not disabled. The Formatter also supports logging an arbitrary number of
userdefined columns. If the Formatter is configured to have more than one
(userdefined) column the data to log has to be preformatted with the
formatMultiColumn method.
