Release 0.0.4

Feature: Option to elide ignored field values

Eliding values of ignored fields can help to declutter the
visualisation. This can now be done at the ObjectMatcher level:

Matcher matcher = object()
    .elideIgnoredFieldValues(true)
    .with("a", eq("x"))
    .with("b", eq("y"))
    .build();

Bugfix: Result interface is now public
