Setup

There are a couple of items to set up.

Controller

class ApplicationController extends Controller
{
	//You Can change the layout here. 'application' is default.
	//Change to null to have no layout.
	//protected $pr_layout = 'my-cool-layout';

	/**
	 * Setup filters
	 *
	 * @return void
	 * @author Justin Palmer
	 **/
	public function __construct()
	{
		parent::__construct();
		$this->filters()->before('authenticate');
	}

	/**
	 * Authenticate the user so that there is a connection and a user.
	 *
	 * @return void
	 * @author Justin Palmer
	 **/
	public function authenticate()
	{		
		try{
			if($this->params('pr-plugin-twitter-id') === null)
				throw new Exception();
			$this->user = new TwitterUser();

			$r = $this->user->find($this->params('pr-plugin-twitter-id'));

			$this->user->props((array)$r);

			$connection = new PhrailsTwitter($this->user->token, $this->user->secret);

			$this->tuser = $connection->get('account/verify_credentials');
		}
		/*If we can't find the record or there is no session for this user.  Fall out.*/
		catch(RecordNotFoundException $e){$this->reset();}
		catch(Exception $e){$this->reset();}
	}
	/**
