/**
 * Optional Answer that adds partial mocking support
 * 

* {@link Answer} can be used to define the return values of unstubbed invocations. *

* This implementation can be helpful when working with legacy code. * When this implementation is used, unstubbed methods will delegate to the real implementation. * This is a way to create a partial mock object that calls real methods by default. *

* As usual you are going to read the partial mock warning: * Object oriented programming is more less tackling complexity by dividing the complexity into separate, specific, SRPy objects. * How does partial mock fit into this paradigm? Well, it just doesn't... * Partial mock usually means that the complexity has been moved to a different method on the same object. * In most cases, this is not the way you want to design your application. *

* However, there are rare cases when partial mocks come handy: * dealing with code you cannot change easily (3rd party interfaces, interim refactoring of legacy code etc.) * However, I wouldn't use partial mocks for new, test-driven & well-designed code. *
