A class for use by classes which want a factory method.
Inherit from this class to obtain the class() factory method, described below.
BaseClass->mixin_factory() : $factory_object
Gets the associated mixin factory. Generated the first time it is needed.
BaseClass->class( @mixins ) : $package_name
Calls the class() method on the associated mixin factory.
For a facade interface that facilitates access to this functionality, see Class::MixinFactory.
