                   # This acts provides Nested Set functionality. Nested Set is a smart way to implement
                   # an _ordered_ tree, with the added feature that you can select the children and all of their
                   # descendants with a single query. The drawback is that insertion or move need some complex
                   # sql queries. But everything is done here by this module!
                   #
                   # Nested sets are appropriate each time you want either an orderd tree (menus,
                   # commercial categories) or an efficient way of querying big trees (threaded posts).
