Breaking Changes

• Diff result method on IGListIndexPathResult changed. -resultWithUpdatedMovesAsDeleteInserts was removed and replaced with -resultForBatchUpdates (b5aa5e3)

// OLD
- (IGListIndexPathResult *)resultWithUpdatedMovesAsDeleteInserts;

// NEW
- (IGListIndexPathResult *)resultForBatchUpdates;

• IGListDiffable equality method changed from isEqual: to isEqualToDiffableObject: (ab890fc)

• The default NSObject<IGListDiffable> category was removed and replaced with NSString<IGListDiffable> and NSNumber<IGListDiffable> categories. All other models will need to conform to IGListDiffable. (3947600)

• Added support for specifying an end position when scrolling. Bofei Zhu (#196). The IGListAdapter scrolling method changed:

// OLD
- (void)scrollToObject:(id)object
    supplementaryKinds:(nullable NSArray<NSString *> *)supplementaryKinds
       scrollDirection:(UICollectionViewScrollDirection)scrollDirection
              animated:(BOOL)animated;

// NEW
- (void)scrollToObject:(id)object
    supplementaryKinds:(nullable NSArray<NSString *> *)supplementaryKinds
       scrollDirection:(UICollectionViewScrollDirection)scrollDirection
        scrollPosition:(UICollectionViewScrollPosition)scrollPosition
              animated:(BOOL)animated;

                 configureBlock:(IGListSingleSectionCellConfigureBlock)configureBlock

                          atIndex:(NSInteger)index
                   scrollPosition:(UICollectionViewScrollPosition)scrollPosition
                         animated:(BOOL)animated;
