iOS UI for panorama capture

Before we delve into the OpenCV code for turning an image collection into a panorama, we will first build a UI to support the easy capture of a sequence of overlapping images. First, we must make sure we have access to the camera as well as saved images. Open the Info.plist file and add the following three rows:
