From: Derrick Stolee <redacted> As we add more embedded members with type 'struct list_objects_filter_options', it will be important to easily perform a deep copy across multiple such structs. Create list_objects_filter_copy() to satisfy this need. This method is recursive to match the recursive nature of the struct.
