changed rendering on listview to have a collection of commentviews and handle rendering when adding new elements.  Before, the view iterated over all collection elements even if only one item was added or removed.  Now when adding and removing no iteration is needed since rendering is delegated to the commentview and listview only subscribes to add events on the model collection.  Additionally created a new method on formview to reset the singleton instance and clear/rebind events appropriately when editing/creating a comment.
removed console.log deubg on commentview.js
