Discussion of [UITableViewDataSource tableView canEditRowAtIndexPath]
The method permits the delegate to exclude individual rows from being treated as editable. Editable rows display the insertion or deletion control in their cells. If this method is not implemented, all rows are assumed to be editable. Rows that are not editable ignore the editingStyle property of a UITableViewCell object and do no indentation for the deletion or insertion control. Rows that are editable, but that do not want to have an insertion or remove control shown, can return UITableViewCellEditingStyleNone from the tableView:editingStyleForRowAtIndexPath: delegate method.
