public class CmsHistoryVersion
extends java.lang.Object
implements com.google.gwt.user.client.rpc.IsSerializable
```
Bean representing a file version for the history dialog.
Since the history dialog can also display offline resources, or resources read from the Online project without a historical version id, this class is needed rather than a single integer to represent a version.
