 *  This simple widget returns a simple twitter feed using standard OAuth now 
 *  required by Twitter's 1.1 API.
 *
 *  To use this, you must first set up an app in the developer tools at http://dev.twitter.com/apps
 *  Just sign in with your twitter account.
 *  Use the website that is going to access the feed as the app name and website.
 *  Once created, create Token keys and insert them in the appropriate fields at line 61.
