            Maintains comments and new comments can be added.
    
            The main architectural change is that Line elements are no longer necessarily
            siblings. Each physical line is now in a LineContainer and LineContainers are
            siblings. Each Line corresponds to a Line in the unified diff and has an id (e.g. line12).
            A Line can be a LineContainer or a child of a LineContainer.
    
            In this way, converting to side-by-side and, in the future, back to unified is non-lossy.
