/*
  Update: 21-06-2010
  The basic authentication service for twitter is going down at the end of the week.
  To continue using that program, the code has been updated to use http://supertweet.net which acts as an API proxy.
  Simply visit the website to setup your twitter account for this API.
  See: http://www.supertweet.net/about/documentation
