Creates OAuth request using Dino Chiesa's class. It then uses Json.net to deserialize the json from twitter in to a tweet object which is then printed to screen.

// TwitPic/OAuth.cs | |
// | |
// Code to do OAuth stuff, in support of a cropper plugin that sends | |
// a screen snap to TwitPic.com. | |
// | |
// There's one main class: OAuth.Manager. It handles interaction with the OAuth- | |
// enabled service, for requesting temporary tokens (aka request tokens), as well | |
// as access tokens. It also provides a convenient way to construct an oauth | |
// Authorization header for use in any Http transaction. | |
// | |
// The code has been tested with Twitter and TwitPic, from a desktop application. | |
