This example program shows some features enabled by the new annotation-basedconfiguration and mapping APIs in codes-base, as well as support for them incodes-net. The example does not exhaustively show all new features added - formore details, see configuration.h, codes-mapping.h, and model-net.h incodes-net.Specifically, some features shown are:* Use of annotated configuration to initialize three separate network models. Note that they are all the same network model, just with different parameterizations. This includes both the configuration file itself as well as interaction in the code between components with different annotations.* Addressing at various levels in both LP type-specific namespaces and model-net namespaces (network id, annotation tuples).* The updated registration/configuration sequence in main.
