All Implemented Interfaces:

```
public class LogUI
extends javax.swing.JFrame
implements ChainsawViewer, SettingsListener
```
The main entry point for Chainsaw, this class represents the first frame that is used to display a Welcome panel, and any other panels that are generated because Logging Events are streamed via a Receiver, or other mechanism.
NOTE: Some of Chainsaw's application initialization should be performed prior to activating receivers and the logging framework used to perform self-logging.
DELAY as much as possible the logging framework initialization process, currently initialized by the creation of a ChainsawAppenderHandler.
