UICollectionView w/ NSFetchedResultsController & NSBlockOperation. Idea originated from Blake Watters (https://github.com/AshFurrow/UICollectionView-NSFetchedResultsController/issues/13)

	- (void)controllerWillChangeContent:(NSFetchedResultsController *)controller
	{
	self.shouldReloadCollectionView = NO;
	self.blockOperation = [[NSBlockOperation alloc] init];
	}

	- (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id<NSFetchedResultsSectionInfo>)sectionInfo
	atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type
	{
	__weak UICollectionView *collectionView = self.collectionView;
