This is adapted from Erica Sadun's explode code in her book "iPhone Developer's Cookbook".
It takes any UIView-based element and exposes all of the subviews and their subviews, etc.
Its a good way to dig into UIKit elements as well as debug your own UIView-based code.
In code, always set level to zero.
