Ez Template Odom movements vs Drive Movements

I started using Ez temp this year for high stakes. I have read most of the api, but I am still a little confused. I did not have the resources or space to implement tracking wheels in my drive base this year but i am planning to use them in push back. I was wondering what the difference is between odom movements and drive movements in Ez temp? I was also wondering if the drive movements by default take the tracking wheels into account once they are set up or if i need to do anything else besides adding them into the chassis constructor?
