Ryan McGrath 10c513edad
A rather large and not very clean update.
- Adds support for NSSplitViewController.
- Reworks NSMenu support to be cleaner with enum variants.
- Reworks the Foundation underpinnings to be a bit safer and more clear
  in how they're used and passed around.
- Changes to docs structure for push towards v0.1.
- Examples updated to account for changes.

//! This example implements a basic macOS Calculator clone. It showcases:
//!
//! - A single-window app
//! - Button handling
//! - Autolayout
//! - Message dispatching
//! - Global key/event handling
//!
//! It does not attempt to be a good calculator, and does not implement the
//! extended Calculator view.
