public class AnsiPrintStream
extends FilterPrintStream
```
A ANSI print stream extracts ANSI escape codes written to a print stream and calls corresponding process* methods.
For more information about ANSI escape codes, see Wikipedia article
This class just filters out the escape codes so that they are not sent out to the underlying OutputStream: process* methods are empty. Subclasses should actually perform the ANSI escape behaviors by implementing active code in process* methods.
