/**

 * The Property pattern is also known as Prototype inheritance.
 * <p>
 * In prototype inheritance instead of classes, as opposite to Java class inheritance, objects are
 * used to create another objects and object hierarchies. Hierarchies are created using prototype
 * chain through delegation: every object has link to parent object. Any base (parent) object can be
 * amended at runtime (by adding or removal of some property), and all child objects will be
 * affected as result.
 * <p>
 * In this example we demonstrate {@link Character} instantiation using the Property pattern.
