Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface CuratorCacheListener
```
Listener for CuratorCache events. The main functional interface is general purpose but you can build event specific listeners, etc. using the builder. Note: all listeners are wrapped in CuratorFramework.runSafe(Runnable) when called.
