/**
* Purpose:Stores the answer to a simple yes/no question.
*
* 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.
*
* 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.
*
* I.e. in a method that gets something, might want some clue after as to
* from where that something was gotten from.
