The minimalist yet fully featured Twitter API class.

Get RESTful data by accessing members of this class. The result
is decoded python objects (lists and dicts).
http://apiwiki.twitter.com/

Examples::
-
+
twitter = Twitter("hello@foo.com", "password123")
-
+
# Get the public timeline
twitter.statuses.public_timeline()
-

# Get a particular friend's timeline

+
# Also supported (but totally weird)
twitter.statuses.friends_timeline.billybob()

Searching Twitter::
-

# The screen name of the user who wrote the first 'tweet'

Getting raw XML data::

format="xml" to the Twitter object when you instantiate it:
-

twitter = Twitter(format="xml")
-
+
The output will not be parsed in any way. It will be a raw string
of XML.
