The Stage class represents an editing context which includes a collection of Scenes.
        The main stage contains all the currently open regular Scenes, while a Prefab stage contains a preview Scene used solely for editing the Prefab in.
The breadcrumbs shown in the Scene view when in Prefab Mode each represent an individual stage. Those with a Prefab icon represent Prefab stages.
