IMessageEditorTabFactory

```
public interface IMessageEditorTabFactory
```
Extensions can implement this interface and then call IBurpExtenderCallbacks.registerMessageEditorTabFactory() to register a factory for custom message editor tabs. This allows extensions to provide custom rendering or editing of HTTP messages, within Burp's own HTTP editor.
