Summary: This pull request removes the `sectionForSectionController:` method from the `IGListCollectionContext` protocol so that the protocol is exclusively for presentation methods. This should not add new functionality, but rather makes the index directly accessible on the section controllers themselves. This change makes sense because at no time will there be an update to the list that the list adapter is unaware of and so it will always be able to set and update any indexes for a section controller that has changed. Issue fixed: #609 - [X] All tests pass. Demo project builds and runs. - [X] I added tests, an experiment, or detailed why my change isn't tested. - [X] I added an entry to the `CHANGELOG.md` for any breaking changes, enhancements, or bug fixes. - [X] I have reviewed the [contributing guide](https://github.com/Instagram/IGListKit/blob/master/.github/CONTRIBUTING.md) Closes https://github.com/Instagram/IGListKit/pull/671 Reviewed By: jessesquires Differential Revision: D4942159 Pulled By: amonshiz fbshipit-source-id: d648cfdd381cbf1d9ee7ff549ae27d2972a84622
