This allows our UI test runner to fetch the catalog by convention tree at runtime in order to generate dynamic test runners that walk the entire catalog by convention tree without requiring maintenance of an explicit list of breadcrumbs.
In this change I have replaced the explicit list of components with such a dynamic walker. In a follow-up change we will be able to dynamically walk through every node of the three and take screenshots. In a subsequent change from there we may allow certain nodes to implement "testActionStart" and "testActionStop" methods that allow the test runner to invoke certain canonical actions automatically (e.g. present a dialog).
A couple examples are flaky, so a new convention has been added to those examples of providing a "flaky" tag on the example's metadata. If this flag is YES, then the example will not be snapshotted.

We recommend using `initWithDefaults` and we should follow the recommendation. This change removes all usage of `init` within MDC components in order to let us remove that initializer from the public surface.
