// Homework 25, challenge: finish this package, or replace these functions with
// three of your own. Suggestions:
//
//   Shout(s)         s in upper case with "!" added
//   Echo(s, n)       s repeated n times with spaces between
//   ReverseWords(s)  the words of s in reverse order
//
// The third one is a stretch. Pick something simpler if needed.
