Approach to tire physics implementation

This project uses Pacejka and LUT (Look up table) for the minimum physics parameter unit. And most of the physics parameters are culculated as interprate 2 parameters (Pacejka, LUT) by additional float type parameters (slip angle, slip ratio, yaw of vehicle etc ...) in order to behave vehicle as more complex.
