21  * Implementation of {@link org.apache.hivemind.ServiceImplementationFactory} that can instantiate
22  * an object and then configure its properties.
23  * <p>
24  * Some thought has been given to using bytecode generation to create properties for messages,
25  * extension point id, and so forth. This is being avoided because it undermines the ability to test
26  * service implemenations as POJOs, outside the framework of HiveMind.
27  * <p>
28  * Instead the service is configured by means of the implementation's constructor and setter
29  * methods.
