Summary:
Adding a working range example to the example app. This example:
- Displays a list of images downloaded from unsplash.it
- Create 20 uniquely-random sized objects
- When section controllers enter the range, create a data task to download the image
- When finished, store image in `downloadedImage`
- Set in cell if cell is visible
- Don't create task if already downloaded or task created
- Cancel task when section controller is destroyed
- Show a spinner cell while downloading the image
