Chaining methods

.write(chunk, [encoding], [callbak])

• chunk (string)
• encoding (string): like the encoding settings in writeable stream. http://nodejs.org/api/stream.html#stream_writable_write_chunk_encoding_callback
• callback (function): callback function settings in writeable http://nodejs.org/api/stream.html#stream_writable_write_chunk_encoding_callback

.end([string], [encoding], [callback])

Same as .write method, but string is also optional.
