DesignPattern::Factory::Creator is the superclass of DesignPattern::Factory::ConcreteCreator. That is, ConcreteCreator inherits all methods from Creator, but can override these methods by implementing its own methods.

From GOF, the DesignPattern::Factory::Creator class:

- declares the factory method, which returns an object of type DesignPattern::Factory::Product. DesignPattern::Factory::Creator may also define a default implementation of the factory method that returns a default DesignPattern::Factory::ConcreteProduct object.

- may call the factory method to create a Product object.

Constructor for this class. Usage:

  my $object = DesignPattern::Factory::Pattern->new();

The default FactoryMethod just dies with an error, thus ensuring that all subclasses implement a working version of this method.

Calls FactoryMethod() and stores the result.
