Add class consistency_checker for domview_ui.
- consistency_checker is to check consistency of the DOM-tree
associated with a domview_ui.
- It is so closed to domview_ui, so it may access private
variables.
- But, it uses public interface of domview_ui if possible.
- consistency_checker is not integrated to domview_ui for separating
functions of consistency checking from the domview_ui. It collects
relative logic into a place and setups a boundary from others.
