This tweet component is a first step. It shows the user-timeline of a given user plus tweets that the user replied to. It shows only public tweets, thus no auth is needed. You can enter another user to display its tweets, but the users tweets muts be unprotected, otherwise the tweets wouldnt be visible without auth.
Next step towards a client would be to figure out, how the auth stuff works, which looks somewhat complicated.. x) More infos about that probably soon in this blog.
