Divided work for basic stuff, and discussed how actual classes are divided.

• The environment, or GolfWorld? class. Has data structures for triangles and the ball.
• The CollisionDetector? class. Has functions that accept triangles and the ball, return any data we need from collisions, and what-have-you.
• The ball as its own class, with CollisionDetector? as a friend. The collision detector can then manipulate the ball's velocity and stuff.

Well, because I don't know how C++ vectors work, there's a bug in the world destructor. This note is mainly here for my reference so I can find it later. I also massaged the files to make dependencies work, and added return false to all the undone collision detections so we could at least get a build.

Instead of just boolean collision detection functions, do we want two sets: alphaCollide to return the time at which the collision will take place (1.0 being never) and normalCollide to return the normal vector it could occur with? Then in our timestep function, we call alphaCollide on all the triangles, decide which will collide first, then normalCollide on just that one.
