// enhancements:  
//   1. let the user play repeatedly
//   2. add a list of "used" words so that the same word is not used twice
//   3. add another boolean array of guessedLetters, 26 elements, all initially false, as the user enters each letter,
//        set the corresponding array element to true (its been guessed) and in getGuess, data verify that the letter input has
//        not already been guessed
//   4. move this code to the GraphicsSkeleton and make this a graphical game where the hangman is drawn in the Graphics area
