RepositoryController (Issue Tracking)

```
public interface RepositoryController
```
Provides access to an Repository UI.
Every Repository is expected to provide an UI to create or change its attributes.

When creating or editing a new Repository instance, the UI is presented in a modal dialog with the necessary Save button to trigger the RepositoryController.applyChanges() method.
