/*
* ---- How Postprocessing works for the reference manager ----
* - When the manager is first added to the scene, all top-level dependencies are added to the manager (AddManagerToScene).
* - When the manager is first added to the scene, all prefabs with ES3Prefab components are added to the manager (AddManagerToScene).
* - All GameObjects and Components in the scene are added to the reference manager when we enter Playmode or the scene is saved (PlayModeStateChanged, OnWillSaveAssets -> AddGameObjectsAndComponentstoManager).
* - When a UnityEngine.Object field of a Component is modified, the new UnityEngine.Object reference is added to the reference manager (PostProcessModifications)
* - All prefabs with ES3Prefab Components are added to the reference manager when we enter Playmode or the scene is saved (PlayModeStateChanged, OnWillSaveAssets -> AddGameObjectsAndComponentstoManager).
* - Local references for prefabs are processed whenever a prefab with an ES3Prefab Component is deselected (SelectionChanged -> ProcessGameObject)
