        * gal/a11y/e-table/Makefile.am: add new files.
        * gal/a11y/e-table/gal-a11y-e-cell.c: (gal_a11y_e_cell_construct):
        set the right role.
        * gal/a11y/e-table/gal-a11y-e-table-item-factory.c: new file.
        (gal_a11y_e_table_item_factory_get_accessible_type),
        (gal_a11y_e_table_item_factory_create_accessible),
        (gal_a11y_e_table_item_factory_class_init),
        (gal_a11y_e_table_item_factory_init),
        (gal_a11y_e_table_item_factory_get_type): factory for the table item
        a11y object. in create_accessible, we judge the type of widget
        then set correct role.
        * gal/a11y/e-table/gal-a11y-e-table-item-factory.h: ditto.
        * gal/a11y/e-table/gal-a11y-e-tree-factory.c: new file.
        (gal_a11y_e_tree_factory_get_accessible_type),
        (gal_a11y_e_tree_factory_create_accessible),
        (gal_a11y_e_tree_factory_class_init),
        (gal_a11y_e_tree_factory_init), (gal_a11y_e_tree_factory_get_type):
        factory for a11y object of etree. Mostly copyed from
        gal-a11y-e-table-factory.c.
        * gal/a11y/e-table/gal-a11y-e-tree-factory.h: ditto
        * gal/a11y/e-table/gal-a11y-e-tree.c: (init_child_item),
        (et_ref_accessible_at_point), (et_get_n_children), (et_ref_child),
        (et_class_init), (et_atk_component_iface_init), (et_init),
        (gal_a11y_e_tree_get_type), (gal_a11y_e_tree_new):a11y object for
        etree object, mostly copied from gal-a11y-e-table.c. init_child_item
        set correct role for the table item.
        * gal/a11y/e-table/gal-a11y-e-tree.h: ditto.
        * gal/e-table/e-table-item.c: (eti_class_init): register factory
        for table item a11y object.
        * gal/e-table/e-tree.c: (e_tree_get_item), (e_tree_class_init):
        add new access fuction to get the table item of etree.
        * gal/e-table/e-tree.h: ditto
