020/**
021 * Implementation of {@link org.apache.hivemind.ServiceImplementationFactory} that can instantiate
022 * an object and then configure its properties.
023 * <p>
024 * Some thought has been given to using bytecode generation to create properties for messages,
025 * extension point id, and so forth. This is being avoided because it undermines the ability to test
026 * service implemenations as POJOs, outside the framework of HiveMind.
027 * <p>
028 * Instead the service is configured by means of the implementation's constructor and setter
029 * methods.
