*
* The hiearchy for a model called Thing would start with an empty interface
* called Thing.Partial that extends {@link PartialModel}. For every sub-group
* of Thing fields that are sent/received together, there would be an interface
* extending Thing.Partial that declares getter methods for those fields only.
*
* At the bottom of the hiearchy would be an interface called Thing.Complete
* that extends {@link Model} and ALL of the Thing parts. Any fields that are not
* declared in any of the parts should be declared in the complete model.
*
* Fields can be shared among different parts of the same model, as long as they
* have identical signatures in all of the parts where they appear.
*
* This system ties together all the parts of a model in a type-safe way, ensuring
* that the fields stay in sync. Model classes should be created for specific cases,
* and only implement the interfaces containing the fields that they use, avoiding
* empty fields and nulls.
