@Sortable on a class Foo will add "Comparable<Foo>" to the list of implemented interfaces and a "compareTo(Foo other)" method.
If you also implement the raw Comparable interface manually you will need to also add a "compareTo(Object other)" method but the raw version is not required or typically recommended. Cheers, Paul.
