/// row can possibly have some action. The section title is "Shortcuts".

/// configure each cell appropriately. Since this is intended as a
/// static section, subclasses should only need to implement the
/// \c viewControllerToPushForRow: and/or \c didSelectRowAction: methods.

/// then it will provide a view controller from \c viewControllerToPushForRow:
/// automatically for rows that are a property/ivar/method.
