Ya these old docs suck (copy-pasted). Will use better words.

_reusableViewSectionControllerMap since this now is not just cells?

naming again to reflect this is generic over UICollectionReusableView and not just cells

This was a little bit of an invasive change with the display handler, but I think that this is the right call. When sending display events for objects, we should account for the supplementary view as part of the section controller. This is especially useful for headers and footers.
Note that this wont effect the working range API at all.
Fixes #300
