Example / Productivity Tool - Saving video to iOS Simulator

Wrote a 5 min. app to save video from a URL into the Photo Gallery. This is a convenient way to load your iOS simulator with video content, if you need it for testing. Hopefully this will be useful to someone beside me. ;)

To use this yourself, create a new mobile app and replace app.js with this code. Run in your simulator and you're done. Then, enter in a valid URL and press the button. I find it easiest to turn on web sharing on your computer and just pull from your local device. But, this should work with any valid URL.
