What it is:

• class to extract still images and metadata from GIF animations
• a port of 'gif-images' from Racket to Objective-C
• me testing the waters with Objective-C, Xcode, iOS

Status: DecomposeGIF class is complete. Thank you ARC. Time to try and roll it up with a GUI!

Test file structure: The initial unit tests are based on this file:
