Required Methods

fn find_items(&self, f: Box<Fn(&String) -> bool>) -> Vec<(String, String)>

TODO

NOTE: This is not the most efficient interface to extract baggage items. The iterator interface cannot cleanly be used because we want TextMapCarrier trait objects (which do not allow generics).

If a better interface comes up re-evaluate this method.
