/**
* Composition over inheritance. The Bridge pattern can also be thought of as two layers of
* abstraction. With Bridge, you can decouple an abstraction from its implementation so that the two
* can vary independently.
*
* In Bridge pattern both abstraction ({@link Weapon}) and implementation ( {@link Enchantment})
* have their own class hierarchies. The interface of the implementations can be changed without
* affecting the clients.
*
*
In this example we have two class hierarchies. One of weapons and another one of
* enchantments. We can easily combine any weapon with any enchantment using composition instead of
* creating deep class hierarchy.
