ComponentVisibility (zay-es-net 1.5.2 API)

```
public interface ComponentVisibility
```
Controls the client visibility of certain component instances. For certain types of components, it may be limited what the client can actually see at any given time based on location, privileges, etc.. These ComponentVisibility strategy objects can control this by intercepting the normal component-retrieving calls and returning null instead. Additionally, it can be called occasionaly to generate the component removal events that the client will need to see when a component is no longer visible.
