2004-11-08  Steven Zhang <steven.zhang@sun.com>

        Implement accessible feature for e-minicard and e-mini-card-view.
        Add get_n_children, ref_child, ref_state_set, atk_selection_interface,
        and action_interface for ea-minicard-view and ea-minicard

        *ea-minicard-view.c:
        (ea_minicard_view_get_n_children),
        (ea_minicard_view_ref_child),
        (ea_minicard_view_ref_state_set),
        (atk_selection_interface_init),
        (selection_interface_add_selection),
        (selection_interface_clear_selection),
        (selection_interface_ref_selection),
        (selection_interface_get_selection_count),
        (selection_interface_is_child_selected),
        (atk_action_interface_init),
        (atk_action_interface_do_action),
        (atk_action_interface_get_n_action),
        (atk_action_interface_get_description),
        (atk_action_interface_get_name).
