User interface classes for CheckStyle. Currenly this is mainly a gui to aid Check developers.

This is definately work in progress. Here are some ideas where you could help:

- Add a read only editor field that highlights the selected AST node.
- Clicking in the editor field could open the corresponding tree path.
- Add a configuration GUI that can be used in all IDE plugins (well, err.., except Eclipse).
- Add ability to execute individual Checks and display the error messages.
- Add a GUI for the {@link com.puppycrawl.tools.checkstyle.api.FileContents}.
- Add ability to define a Check by example (another one of those crazy ideas... :-)
