cacao/examples/window_controller.rs

//! This example showcases setting up a basic application and window controller.
//! A Window Controller is backed by `NSWindowController`, and typically used in scenarios where
//! you might have documents (backed by `NSDocument`) that you're working with.
//!
//! If you're not using that, you can probably get by fine with a standard `NSWindow`.
