WebAppInit (zk 10.0.0-Beta API)

All Known Implementing Classes:

AuRedirect, WebAppInit, WebAppInit, WebSocketWebAppInit
```
public interface WebAppInit
```
Used to initialize a ZK application when it is created.
Notice that, when init(org.zkoss.zk.ui.WebApp) was called, WebApp has been created. In other words, it is too late to change the implementation class of UiEngine via Configuration. Rather, use WebAppCtrl.setUiFactory(org.zkoss.zk.ui.sys.UiFactory) and other methods instead.
How this interface is used.
1. First, you specify a class that implements this interface in WEB-INF/zk.xml as a listener.
2. Then, even time a ZK application is created, an instance of the specified class is instantiated and init(org.zkoss.zk.ui.WebApp) is called.
