+/// @brief A class designed to wrap callback batons so they can cleanup
+///        any acquired resources
+///
+/// This class is designed to be used by any objects that have a 
+/// callback function that takes a baton where the baton might need to
+/// free/delete/close itself.
+///
+/// The default behavior is to not free anything. Subclasses can 
+/// free any needed resources in their destructors.
