Significantly improved execution time especially for large storyboard files. In order to determine if a class can be imported, it now looks for a file of the same name as the class (e.g. MyCustomClass.h). While this isn’t perfect, it does seem to handle most of the cases at a significant performance boost. In order to show how dequeueImageCellForIndexPath:ofCollectionView: can return a CGTAFlagCollectionViewCell instance, the demo app has been updated to separate CGTAFlagCollectionViewCell into its own file.
