A property that has a reference to another model instance. A "Foreign Key" if you will.
For full functionality a ModelInstanceFetcher must be provided in the config.
This property has complex functionalities.
When a model calls "instance.get.whatever()" to get the value of a ModelReferenceProperty, it uses the model fetcher
to retrieve the model. (Could be saved elsewhere, or a database). When the promise is awaited, the value returned
is a ModelInstance object.
However, when toObj() is called on that same instance, only the primary key value is returned. This is so that
when you call toObj() on the main instance, the "foreign key" gets filled in.
