I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

#HW 1-2: Rock-Paper-Scissors
In a game of rock-paper-scissors (RPS), each player chooses to play Rock (R), Paper (P), or Scissors (S). The rules are: R beats S; S beats P; and P beats R. We will encode a rock-paper-scissors game as a list, where the elements are themselves 2-element lists that encode a player's name and a player's selected move, as shown below:
[ ["Armando", "P"], ["Dave", "S"] ] # Dave would win since S > P
Part A: Write a method rps_game_winner that takes a two-element list and behaves as follows:
If the number of players is not equal to 2, raise WrongNumberOfPlayersError.
