Attempting to add tags in example results in an NSInternalInconsistencyException:

there is a problem with the performBatchUpdates. You can change in AKTagsLookup.m

-(void)filterLookupWithPredicate:(NSPredicate )predicate { self.predicate = predicate; NSMutableArray filteredTags = [[self.tagsBase filteredArrayUsingPredicate:self.predicate] mutableCopy]; self.tagsView.selectedTags = filteredTags; [self.tagsView.collectionView reloadData]; [self.tagsView.collectionView layoutIfNeeded]; }

I have made some changes, resetting buggy PR's accepted by mistake. Also refreshed tag 1.0.1 - you can use the example project from that tagged commit (75d010e661dbe646e97b5c68101b35538445563b), note the issues list though
