 Bits of the twitter API that have been implemented and bits that need
 implementing in twitter.py
-----------------------------------------------------------------------

o See http://groups.google.com/group/twitter-development-talk/web/api-documentation

o API methods are wrapped in the Twitter class in twitter.py. In order to implement
  a new one, use a naming scheme such as status_public_timeline or friendship_create
  for the method name. The implementing method should accept arguments which mirror
  the arguments required in the API docs.
