 * Helper class to represent an answer/result returned by some nested class code to its surrounding
 * scope. It is basically just a boxed value of some
 * other type. Typical use would be to be able to declare a final variable outside of a runnable
 * block so that the boxed value can be set from inside the runnable block. This is to
 * get around the restriction that a variables used from inside inner classes must be declared final.
