Elo<T> class

Simplified Elo rating.

Similar to FIDE (Chess), just takes an n value, implying that a player that has n more points is 10 times stronger.

The k factor determines how aggressively a rating is changed after new results. FIDE uses different ratings for new and old players (allowing bigger changes in the beginning, and then slowing down the changes). This class does not support changes.

Also, there is no way to use a different initial rating. FIDE, for example, computes the initial rating out of the first games.

See https://blog.mackie.io/the-elo-algorithm for a good description of the algorithm.
