// twittertot is a jquery plugin that fetches a user's unprotected tweets for display on a website. 
// Configure the username and number of tweets. Tweets are displayed as a list by default or can
// be cycled one at a time by passing {cycle: true} as an option.
//
// Usage: (1) with default options: $('#tweets').twittertot();
//       (2) pass options with a hash $('#tweets').twittertot({username: 'biz', count: 10, cycle: true});
