* A base class for objects which optionally provide properties.

- * The concrete derived class is responsible for:
- * 1) Adding & removing an object from the scene-graph. The OnSceneObjectAdd() and OnSceneObjectRemove()
- * methods should be called by the derived class, to trigger observer callbacks.
- * 3) Implementing the GetSceneObject() methods, used to access the scene-object.
- * 4) Providing access to properties stored by the scene-graph object. These should match the properties
- * reported by the base Dali::Internal::Object methods.
- *
+ * The derived class should either:
+ * a) Create their own scene-graph object and pass it to Object constructor.
+ * b) pass nullptr to Object constructor, in this case Object will create default scene object for property handling
