code cleanup. found a limitation with the current comment tree rendering where if only a subset of all comments are fetched, then it's possible for the tree to never finish rendering because there will be comments referring to parent nodes not present in the items fetched. Since fetching is set to 100, added a kludge where we iterate a maximum 10 generations
