EqualsWrapper (JSONCoder 0.1.21 API)

```
public interface EqualsWrapper<T>
```
For eBay BO, there is no way to check actual equality of two BO objects. So this wrapper is to solve this issue. To override the hashCode() and equals() methods.
This class is using Wrapper pattern and Prototype pattern.
It's a prototype, so that client can create a single prototype instance and set to BeanCoderContext.
At encoding runtime, the actually wrapper object will be cloned from the prototype object.
