        The scan scene method is executed once at startup and its purpose is
        to analyze the current scene and return a list of references that are
        to be potentially operated on.

        The return data structure is a list of dictionaries. Each scene reference
        that is returned should be represented by a dictionary with three keys:

        - "node": The name of the 'node' that is to be operated on. Most DCCs have
          a concept of a node, path or some other way to address a particular
          object in the scene.
        - "type": The object type that this is. This is later passed to the
          update method so that it knows how to handle the object.
        - "path": Path on disk to the referenced object.

        Toolkit will scan the list of items, see if any of the objects matches
        any templates and try to determine if there is a more recent version
        available. Any such versions are then displayed in the UI as out of date.
