 * 
 * Whereas Singleton design pattern introduces single globally
 * accessible object the Multiton pattern defines many globally
 * accessible objects. The client asks for the correct instance 
 * from the Multiton by passing an enumeration as parameter.
 * 
 * In this example Nazgul is the Multiton and we can ask single
 * Nazgul from it using NazgulName. The Nazguls are statically
 * initialized and stored in concurrent hash map.
