Replacement for NSFileWrapper that loads / saves content on-demand. Understands how to save / serialize objects like ALAsset, UIImage, NSDictionary, etc...
I believe this code is exactly what I'm needing. I've got annoying memory issues with a UIDocument that contains multiple photos/videos that I'm trying to fix. However I'm not certain how to implement this with my current codebase. If you could provide a small sample xcode project, I wouldn't mind writing some documentation and submit it as a pull request once I figure it all out.
