KillRing

```
public final class KillRing
extends java.lang.Object
```
The kill ring class keeps killed text in a fixed size ring. In this class we also keep record of whether or not the last command was a kill or a yank. Depending on this, the class may behave different. For instance, two consecutive kill-word commands fill the same slot such that the next yank will return the two previously killed words instead that only the last one. Likewise yank pop requires that the previous command was either a yank or a yank-pop.
