All Implemented Interfaces:

```
@Entity
public class ContactHistory
extends HistoryEntry
```
A persisted history entry representing an EPP modification to a contact.
In addition to the general history fields (e.g. action time, registrar ID) we also persist a copy of the contact entity at this point in time. We persist a raw ContactBase so that the foreign-keyed fields in that class can refer to this object.
