// Program name: PigLatin
// Description: Class PigLatin accepts user input (a single word, a phrase, or
//    a complete sentence) and converts to 'pig latin,' according to these simplified
//    rules: 1) words starting with vowels have 'way' added to them; and 
//    2) all other words have their first letter moved to the end, with 'ay' tacked on
//    after that.
//
//    The program works for single-letter-words, such as the letter 'a' (which then
//    becomes "away," according to our rules).
//
//    Each line of text input is first tokenized (the StringTokenizer is passed a set
//    of delimiters that includes punctuation) and then the string that comprises 
//    each token is passed to the printLatinWord() method, which contains the 
//    algorithm.
//
//    The complete translated sentence is displayed in a single line in the output area; each 
//    sentence remains in the display.
