/* Twitter Addon for Friendica
*
* Author: Tobias Diekershoff
* tobias.diekershoff@gmx.net
*
* License:3-clause BSD license
*
* Configuration:
* To use this addon you need a OAuth Consumer key pair (key & secret)
* you can get it from Twitter at https://twitter.com/apps
*
* Register your Friendica site as "Client" application with "Read & Write" access
* we do not need "Twitter as login". When you've registered the app you get the
* OAuth Consumer key and secret pair for your application/site.
*
* Add this key pair to your global config/addon.config.php or use the admin panel.
*
* 'twitter' => [
* 'consumerkey' => '',
* 'consumersecret' => '',
* ],
*
* To activate the addon itself add it to the system.addon
* setting. After this, your user can configure their Twitter account settings
* from "Settings -> Addon Settings".
*
* Requirements: PHP5, curl
