        This function is necessary to grab the osg::Group that will contain
        any lights that are requested for allocation. Note that this osg::Group,
        for some reason, should be DIRECTLY under the SceneView. That is, there
        should not be any other nodes between the SceneView and this osg::Group.

        This function is used to request allocation of an osg::Light. The light
        is requested by passing the enumerated value representing the number
        of the light. If the light has not been previously allocated, it is created
        and added to the osg::Group for rendering. The osg::Light is returned
        as a pointer, which may be used to modify the light properties via
        the osg::Light interface.
        
        If the light has been previously allocated, it is returned as a pointer.
        
        Note that if this module has not been initialized with the init() function,
        NULL will be returned instead of an osg::Light.
