'''
This is a proof-of-concept script for tagging photos with location data on iOS.
* First, it shows all photos that have no location data *and* are editable.
* Then, a grid of photos in temporal proximity is shown. You can pick multiple photos here.
* When you tap Done, the photo you selected first will get tagged with the average location of the photos you picked in the second step.
