     * 1) examine each charactor of the QA[] array and shift the character by the shift variable amount 
     *    (use modulus to wrap character around)
     * 2) save each encrypted character to ArrayList - 
     * 3)  3 variables you'll use are al[] array, QA[] array and encryptedQuote arraylist
     * 4) display encrypted text to screen by reading through the arraylist
