 				This function is used for plugins that edit specific object types (nodes or resources). It requests the editor to edit the given object.
 				[param object] can be [code]null[/code] if the plugin was editing an object, but there is no longer any selected object handled by this plugin. It can be used to cleanup editing state.

 				Implement this function if your plugin edits a specific type of object (Resource or Node). If you return [code]true[/code], then you will get the functions [method _edit] and [method _make_visible] called when the editor requests them. If you have declared the methods [method _forward_canvas_gui_input] and [method _forward_3d_gui_input] these will be called too.
