The processLine definition differs from the base TCPObject class causing the function to never be called. This causes HTTPObject to not function properly, it calls back into the Torque Script with the HTTP headers when it should only be returning the content.
Update README.md

Added T3D 3.5 and Project Manager 2.1 links.
Simply early-outing from denominators near zero was causing tangeants to be filled with garbage data. This alters the functionality to set a floor distance so the rest get's filled out properly.
