Summary: Adding support for a cell deselection API. Trying to make some headway to move and drag+drop support, but also want better stock `UICollectionView` API support. Will also assist eventual `UITableView` support. - Added overridable API to `IGListSectionController` - Support for stacked SC - Breaking, required protocol for binding SC Assists #524 and #184 - [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.
