+  OK - this is a rough and ready prototype of a simple multi-player shoot-em-up.
+  Get a bunch of players in close proximity and issue the following commands...
+
+  /js var redTeam = ['<player1>','<player2>',...etc]
+  /js var blueTeam = ['<player3>','<player4>,...etc]
+  /js var greenTeam = ['<player5>','<player6>,...etc]
+  /js new SnowBallFight({red: redTeam,blue: blueTeam,green: greenTeam},60).start();
+
+  (where <player1> etc are the names of actual players)
+  
+  You specify the teams in the game as an object where each property's name is a team name and 
+  each property's value is the list of players on that team.
+  You specify the duration of the game (in seconds)
+  You kick off the game with the start() method.
+  I need to work on a better in-game mechanism for players to choose teams and start the game
+  but this will do for now.
+
+  When the game starts, each player is put in survival mode and given 192 snowballs. The aim of the 
+  game is to hit players on opposing teams. If you hit a player on your own team, you lose a point.
+  
+  At the end of the game the scores for each team are broadcast. Create a small arena
+  with a couple of small buildings for cover to make the game more fun :-)
