  20  * This class reads in team data for all of the teams in a tournament, stores
  21  * teams in some form of linear list, prints out information about each of the
  22  * teams in the order in which the data was entered, reorders the list so that
  23  * teams are in order on the basis of number of wins (the team with the most
  24  * wins occurs earliest in the list), prints out information about the teams
  25  * based on the revised order of the list, and then sets up and prints the
  26  * first round matches for a round-robin style tournament, in which the team
  27  * with the most wins plays the team with the fewest wins, the team with the
  28  * second most wins plays the teams with the second fewest wins, and so on.
