This "container" is a few hundreds LOC. Please document its real purpose -
acting as RLVC delegate, displaying toolbars, displaying pop-ups etc. 

In fact, I'd argue that this class should be renamed to RLVC, and RLVC ->
RLCollectionViewController. If you choose to rename this, please do it in a
separate CL to preserve diffs.

Done.

I was thinking of reusing the history pattern which is a
HistoryPanelViewController instead of the ReadingListViewControllerContainer and
a HistoryCollectionViewController instead of the ReadingListViewController.
