Suggestion : access to TWTRTweetViewDelegate from TWTRTimelineViewController



It would be convenient to provide access to tweet view delegate messages when using TWTRTimelineViewController.

Suggestion is that TWTRTimelineViewController should have TWTRTimelineViewControllerDelegate protocol (with the same methods as TWTRTweetViewDelegate except didSelectTweet:) or TWTRTweetViewDelegate property that all TWTRTweetView instances will report to, to receive messages about actions on tweets in the timeline.
