Easily display messages on your two-line LCD screen.

• Network accessible: Posting a message on your screen is as easy as a simple curl command.
• Automatic rotation: If you send multiple messages to the screen for display, Twoline will rotate through them for you automatically.
• Automatic paging: Your screen can only show 32 characters at a time? Don't worry; Twoline will page through your message for you.
• Easy color and blinking configuration: Every message can have its own color.
• Message expiration: Can't be bothered to send a DELETE to remove your message when its no longer relevant? Just set your messages's expires key and Twoline will automatically remove the message when it's over.

curl -i -X POST -H "Content-Type: application/json" -d '{"message": "Hello World"}' http://127.0.0.1:6224/message/

Pretty easy, huh?!
