Summary: Prefix all private methods with an underscore. A private method is defined as any method not exposed via an interface or protocol. This will improve the readability of the code and hopefully reduce bugs.

Summary:
* Issue: [IGListAdapter visibleSectionControllers] calls [UICollectionViewLayout layoutAttributesForElementsInRect:] which can be expensive. And since visibleSectionControllers is called in scrollViewDidScroll, it can add up and take a toll on scroll performance. On an iPhone 7, it's in 2-10% of the main-thread samples (using Time Profiler).
* Fix: IGListDisplayHandler conveniently keeps track of visible IGListSectionControllers, so let's just use that. Now, [IGListAdapter visibleSectionControllers] drops to ~0.3% of samples.

Summary:
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.
