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