    @short          implement a container to hold children of frame, task or desktop
    @descr          Every object of frame, task or desktop hold reference to his children. These container is used as helper
                    to do this. Some helper-classe like OFrames or OTasksAccess use it to. They hold a pointer to an instance
                    of this class, which is a member of a frame, task or desktop! You can append and remove frames.
                    It's possible to set one of these frames as active or deactive. You could have full index-access to
                    container-items.
