ResourceCollection (The Adobe AEM Quickstart and Web Application.)

```
@ProviderType
public interface ResourceCollection

Each entry in the collection is represented by a Resource which contains a reference to original resource. That reference Resource can have additional properties (creationDate, etc.)
