NullHook (ScriptBasic for Java 2.0.0 API)

java.lang.Object
- com.scriptbasic.hooks.NullHook

All Implemented Interfaces:

InterpreterHook
```
public class NullHook
extends java.lang.Object
implements InterpreterHook
```
The simplest implementation of the InterfaceHook interface. This implements each of the methods of the interface, each doing nothing.
This hook is used to chain into the hook chain first so that hook classes need not check if there is a next hook object in the chain.
