This example demonstrates a simple Calculator application that is composed of POJO services for each calculator function (add, subtract, multiply and divide).
Each calculator function is a deployable service, and the Calculator has a declared association to each service. The Calculator service becomes 'whole' when it discovers it's required services. The Calculator is a good example on the use of associations and how association based dependency injection can be used.

The example also provides a test client that uses the Rio test infrastructure to create and invoke methods on the Calculator service.
