Code updates

My semester officially ended the last Friday, finally free!, I'll be going back to home today for Fathers day.

Now about some code updates, I redid the basic tracer lines code for OpenGL, which consist of creating a series of lines given the movement of the car from Pos1 to Pos2, of course this could potentially waste a lot of resources, however, each new line is compared with previous one and if they have the same angle the previous line is just extended, additionally you can turn the tracer on and off, here is a nice example of things you can do with it :)Tracer lines are mostly done, and so are sensors, next thing is car scripting, I still not very sure on what approach to take, I could just load the script and execute it each time the car is updated, other way could be by using events, having the user hook to specific events (update, sensor, etc.), or just have them create a class where the function update is called each time the car updates, and so on, this last approach has the advantage that you can use the class for storage (variables). Who knows, I will probably just branch and take all approaches and see what works best then merge it with HEAD and be done with it :)
