Athena::Serializer::ObjectConstructorInterface
Determines how a new object is constructed during deserialization.
By default it is directly instantiated via .new as part of ASR::InstantiateObjectConstructor.
However custom constructors can be defined. A use case could be retrieving the object from the database as part of a PUT request in order
to apply the deserialized data onto it. This would allow it to retain the PK, any timestamps, or ASRA::ReadOnly values.
