Elo Rating System

The Elo Rating System is designed to provide a method for calculating the relative skill levels of players in zero-sum games such as chess and other competitive sports or games. This implementation offers an easy-to-use, flexible system for game developers, competition organizers, and anyone interested in rating systems.

Features

• Initial Rating Setup: Set initial ratings for new players.
• Dynamic Rating Updates: Update ratings based on game outcomes (win, loss, draw).
• Flexible K-Factor Adjustment: Adjust the sensitivity of rating changes.
• Support for Multiple Players: Manage ratings for an arbitrary number of players.
