The django-model-utils package provides us an InheritanceManager that we can apply to the base class when we have a model inheritance tree.
This allows us to retrieve the correct subclasses when querying, rather than simply getting instances of the parent class,
We will add django-model-utils and use this InheritanceManager in this video.
We'll see the two methods it adds to our Django Querysets:
1. select_subclasses()
2. get_subclass()
