BurgerBot is Alive!

This is the initial release of BurgerBot and contains just the basics to make the robot move backward and forward. We'll be adding the range finder code in the next release, and it will be using the i2c version of the ultrasonic HC-SR04 range finder.

The code also contains some essential documentation, so look at <demo1.py> for an example of how to use the Burgerbot class.
