/**
 * Generic interface to be used for configuring mock's answer for a two argument invocation.
 *
 * Answer specifies an action that is executed and a return value that is returned when you interact with the mock.
 * 
 * Example of stubbing a mock with this custom answer:
 *
 * 

 * import static org.mockito.AdditionalAnswers.answer;
 *
 * when(mock.someMethod(anyString(), anyChar())).then(answer(
 *     new Answer2<String, String, Character>() {
 *         public String answer(String s, Character c) {
 *             return s.replace('f', c);
 *         }
 * }));
 *
 * //Following will print "bar"
 * System.out.println(mock.someMethod("far", 'b'));
 * 
 *
 * @param  return type
 * @param  type of the first argument
 * @param  type of the second argument
 * @see Answer
