/**
* The Prototype pattern is a creational design pattern in software development. It is used when the
* type of objects to create is determined by a prototypical instance, which is cloned to produce
* new objects. This pattern is used to: - avoid subclasses of an object creator in the client
* application, like the abstract factory pattern, does. - avoid the inherent cost of creating a new
* object in the standard way (e.g., using the 'new' keyword)
*
* In this example we have a factory class ({@link HeroFactoryImpl}) producing objects by
* cloning the existing ones. The factory's prototype objects are given as constructor parameters.
