Simple network logging Handler.

LogRecords are published to a network stream connection. By default the XMLFormatter class is used for formatting.

Configuration: By default each SocketHandler is initialized using the following LogManager configuration properties. If properties are not defined (or have invalid values) then the specified default values are used.

The output IO stream is buffered, but is flushed after each LogRecord is written.
