Edit: As of June 2017, Riot has changed their API. My API interface, Orianna, is taking longer than expected to update for Riot API V3, and until that update happens this program will not work.
Look up how a player's average GPM changes over the course of the game
Requires external libraries: gson-2.3.1.jar, https://github.com/google/gson Orianna-2.4.3.jar, https://github.com/robrua/Orianna/releases
Requires you get an api key and put it in a file key.txt
