//          "99 Bottles of Beer on the Wall"
//          to the screen
//
// Examples: printBeerVerse(89) should cause the
//           following to be printed to the screen:
// 89 bottles of beer on the wall,
// 89 bottles of beer!
// Take one down, pass it around,
// 88 bottles of beer on the wall!
