/*   Twitter Plugin for Friendika
 *
 *   Author: <NAME>
 *           <EMAIL>
 *
 *   License:3-clause BSD license (same as Friendika)
 *
 *   Configuration:
 *     To use this plugin you need a OAuth Consumer key pair (key & secret)
 *     you can get it from Twitter at https://twitter.com/apps
 *
 *     Register your Friendika 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 .htconfig.php
 *
 *     $a->config['twitter']['consumerkey'] = 'your consumer_key here';
 *     $a->config['twitter']['consumersecret'] = 'your consumer_secret here';
 *
 *     To activate the plugin itself add it to the $a->config['system']['addon']
 *     setting. After this, your user can configure their Twitter account settings
 *     from "Settings -> Plugin Settings".
 *
 *     Requirements: PHP5, curl [Slinky library]
 *
 *     Documentation: http://diekershoff.homeunix.net/redmine/wiki/friendikaplugin/Twitter_Plugin
