Versioned (Gemma Core 1.31.5 API)

All Known Implementing Classes:

ArrayDesignValueObject, ExternalDatabase, ExternalDatabaseValueObject
```
public interface Versioned
```
Interface implemented by entities that are externally versioned.
This allows us to have a common set of attributes and audit events relating to the versioning of entities. Prominent examples are ExternalDatabase and ArrayDesign.
These entities can be made auditable, in which case VersionedEvent can be used to represent events such as a new release, a genome patch update being applied, etc.
