47  * <b>Purpose</b>:Stores the answer to a simple yes/no question.
48  * <p>
49  * Superior to Boolean in that you can pass it to a method as a parameter,
50  * that method sets the value to either true or false, and then see the
51  * answer after.
52  * <p>
53  * I.e. if a method finds the answer to a question while doing some calculations,
54  * it can mark the answer so another method doesn't need to do those calculations
55  * again just to see what the answer is.
56  * <p>
57  * I.e. in a method that gets something, might want some clue after as to
58  * from where that something was gotten from.
