        DeltaAware merge​(DeltaAware d)
        Merge the current Delta instance with a given DeltaAware instance, and return a coherent and complete DeltaAware instance. Implementations should be able to deal with null values passed in, or values of a different type from the expected DeltaAware instance. Usually the approach would be to ignore what is passed in, create a new instance of the DeltaAware implementation that the current Delta implementation is written for, apply changes and pass it back.
        d - instance to merge with, or null if no merging is needed
        a fully coherent and usable instance of DeltaAware which may or may not be the same instance passed in
