*  The object class
*  This is a generic type for storing objects in the scene.
*  Being an abstract class, this class cannot be instantiated.
*  Sphere, Plane etc, must be defined as subclasses of Object
*      and provide implementations for the virtual functions
*      intersect()  and normal().
