 * The MApplication acts as the root of the UI Model. It's children are the

 * own runtime information but also to any registered OSGI service.
 * </p><p>
 * It also owns a number of caches which, while independent of the UI itself are
 * used by the appliecation to populate new windows or to define state that is
 * epected to be the same for all windows:
 * <ui>
 * <li>Keybindings, Handlers, Commands</li>
 * <li>Part Descriptors (to support a 'Show View' dialog...)</li>
 * <li>Snippets of model (such as saved perspectives...)</li>
