OAuth stack middleware.

• session: The request must have session handling accounted for. You can do this by prepending the stack/session middleware to this one.

• credentials: You need to have some sort of OAuth server. By default, stack/oauth will use twitter. But you can change that through the oauth_service.class config parameter.

use Igorw\Stack\OAuth; $app = new OAuth($app, [ 'key' => 'foo', 'secret' => 'bar', 'callback_url' => 'http://localhost:8080/auth/verify', 'success_url' => '/', 'failure_url' => '/auth', ]); 

• /auth
• /auth/verify

• config validation
• tests
• more flexible path config (?)
