/**
* The Chain of Responsibility pattern is a design pattern consisting of command objects and a
* series of processing objects. Each processing object contains logic that defines the types of
* command objects that it can handle; the rest are passed to the next processing object in the
* chain. A mechanism also exists for adding new processing objects to the end of this chain.
*
* <p>In this example we organize the request handlers ({@link RequestHandler}) into a chain where
* each handler has a chance to act on the request on its turn. Here the king ({@link OrcKing})
* makes requests and the military orcs ({@link OrcCommander}, {@link OrcOfficer}, {@link
* OrcSoldier}) form the handler chain.
