function main() {
    var ui = Sudoku.null,
        widget = Sudoku.widget;

    // SC.View initially has no layers, so you'll add your widget to your
    // view's layers so it can display itself and receive events.
    ui.get('layers').pushObject(widget);

    // Next, you'll tell `SC.app` that you want your `SC.View` surface to
    // become the app's user interface ('ui').  Each app has only one active
    // `ui` surface, though you can change it at any time.
    SC.app.set('ui', ui);

    // You can also add arbitary surfaces to the application using
    // `SC.app.addSurface(...)`, but this is for a more advanced tutorial.
