PROJECT: ResKnife
FILE: ICONWindowController.h
PURPOSE: This is the main class of our bitmap resource editor. Every
resource editor's main class implements the
ResKnifePluginProtocol. Every editor should implement
initWithResource:. Only implement initWithResources: if you feel
like writing a template editor.
Note that your plugin is responsible for committing suicide
after its window has been closed. If you subclass it from
NSWindowController, the controller will take care of that
for you, according to a guy named Doug.

2003-07-31 UK Created.
