        Django model mixins and utilities.
        
        InheritanceCastModel
        ====================
        
        This abstract base class can be inherited by the root (parent) model
        in a model-inheritance tree.  It allows each model in the tree to
        "know" what type it is (via an automatically-set foreign key to
        ``ContentType``), allowing for automatic casting of a parent instance
        to its proper leaf (child) type.
        
        For instance, if you have a ``Place`` model with subclasses
        ``Restaurant`` and ``Bar``, you may want to query all Places::
        
        nearby_places = Place.objects.filter(location='here')
        
        But when you iterate over ``nearby_places``, you'll get only ``Place``
        instances back, even for objects that are "really" ``Restaurant`` or
        ``Bar``.  If you have ``Place`` inherit from ``InheritanceCastModel``,
        you can just call the ``cast()`` method on each ``Place`` and it will
        return an instance of the proper subtype, ``Restaurant`` or ``Bar``.
        
        .. note::
        This is inefficient for large querysets, as it results in n
        queries to the subtype tables.  It would be possible to write a
        QuerySet subclass that could reduce this to k queries, where there
        are k subtypes in the inheritance tree.
