+/spectators
+
+ Method: GET
+
+ Behavior: Gets a list of all spectators. A spectator is someone
+ who has started viewing the game (and stated their own
+ name) but isn't directly involved in the game.
+
+ Example data: [ { id: 1, name: "Richard"}, { id: 2, name: "Nancy"} ]
+
+ Note: The IDs of spectators and players are unrelated. If a person
+ initially joins as a spectator and then later joins the game as a
+ player, an unrelated player ID will be generated. From the
+ server's point of view, the events of a spectator leaving and a
+ player joining that happens to have the same name---those two
+ events have nothing to do with each other.
