CharBuf (boon 0.18 API)

java.lang.Object
- java.io.Writer
- - java.io.PrintWriter
  - - org.boon.primitive.CharBuf

All Implemented Interfaces:

Closeable, Flushable, Appendable, AutoCloseable, CharSequence
```
public class CharBuf
extends PrintWriter
implements CharSequence
```
This class is like a StringBuilder but it also pretends to be a PrintWriter. The class existed long before I added PrintWriter cababilities. I did look at the PrintWriter code but any code in this class should be a derivative product. If I copied and/or emulated any technique from PrintWriter, be assured that I give them full credit. I believe at all times the usage was small enough to be covered under "fair use". But to remove any doubt, the comments in question have been deleted.
