Hello, Complex Universal

A sample demonstrating how to create universal applications that will run on both iPhone and iPad devices, by switching the UI based on the UIInterfaceIdiom enum.

This sample differs from the regular Hello, Universal sample in the way UI switching is done. Instead of having one controller manage two separate views depending on the device in use, we employ two different root controllers.

**NOTE: This sample will only work with Xcode 5.0 or above.
