Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface DiffEvaluator
```
Interface used to evaluate two models and their normalized differences and return ValidationEvents that are relative to the new model.
For example, a ValidationEvent is emitted when an operation is removed from a service or resource.
Implementations of this interface are found using Java SPI and automatically applied to the detected differences when creating a ModelDiff.
