Hey! So, this is That One Project I've spent the better part of a year on,
inspired by Ginger/Pepperdork's rating system. I managed to port their system
over at first, then realized I needed something that didn't completely demolish
newer players in bottom half of finishes. That's where CTGP comes in - the 
ranking calculations are ported from their netplay formula, as are the
chances for game speed change (https://wiki.tockdom.com/wiki/Player_Rating).
Through months of testing and troubleshooting, I've developed this tool
for hosts who want to add a competitive edge to their servers and give their
players unique ways to interact with each other via the Rival system. I had a 
FUCKTON of help putting this together, and this wouldn't be here without the
following:

NVJR - Custom intermission scoreboard to accurately reflect rating changes
Snu - Rival indicator code and framework
DarkyBenji & CGB - HUD code for score display and framework for speed switch and
Expert Speed via FreshKart and CGB 200cc
Tyron - Framework for Rival music module via Hornmod, and Hostmod Neo Scoreboard stuff
Shiho - Rival indicator sprites
fickle - Rival system framework via Combi
Pepperdork - Rating system groundwork
Togen, Ashnal, Lighto - Valuable feedback
Jugador - Chat module interop
Callmore, freeman - Scorekeeper framework
LJ Sonic - PRNG Library
The Lab regulars - Playtesting and feedback
Moonlane Club, Scyther's Stream Server, Interdimensional Circuit - Playtesting
and feedback
Mystery Jayne - Playtesting, feedback, and listening to me gush about codemonkey
things
