Source Code for League Overseer
Submitted for April 2016 Riot API Challenge.
Inside the champions folder you require a different file for each champion, the file provided is simply a template. I will fix the need for 130 files in the future.
With League Overseer you can search up player's Champion Mastery and see the top players for each champion.
For the leaderboards, you will need an SQL database. I have included SQL code with the source code to make it easier to create this database. The SQL code is in 'leagueDB.sql' This will automatically add some summoner names to the leaderboards, but new ones will still be able to get added.
