Usage

First, create two players with current ratings. This allows you to get their ratings in a quick way:

use EloRating\Player;

$player1 = new Player(1200);
$player2 = new Player(800);

Next create a match.

use EloRating\Game;

$match = new Game($player1, $player2);

If you chose to set the K for the ELO Score, you can, however the default K is 32:

$match->setK(16);

After the match is complete, you can set the score and run the count method to recaculate the new scores. The score is done for player one, then player two.

$match->setScore(0, 1)
   ->count();

Get players:

$player1 = $match->getPlayer1();
$player2 = $match->getPlayer2();

Get their new ratings after the match:

$newRating1 = $player1->getRating();
$newRating2 = $player2->getRating();
