 // Implements core window manager functionality that could conceivably be shared
 // across multiple window managers implementing superficially different user
 // experiences. Establishes communication with the view manager.
 // A window manager wishing to use this core should create and own an instance
 // of this object. They may implement the associated ViewManager/WindowManager
 // delegate interfaces exposed by the view manager, this object provides the
 // canonical implementation of said interfaces but will call out to the wrapped
 // instances.
 // This object maintains an aura::WindowTreeHost containing a hierarchy of
 // aura::Windows. Window manager functionality (e.g. focus, activation,
 // modality, etc.) are implemented using aura core window manager components.
