Add some form of encoder/odometry

[garyservin]

This is not strictily related to the board but...

If we want to use ROS with the robot, it's mandatory that we have some sort of odometry for the wheels.

One option is to use accelerometers and integrate (x2) the readings to obtain position, but I think that is not such a good Idea

We can use a simple magnet with a Hall efect sensor.

We can also add a gyro in order to help with the error when the robot is turning (e.g. like in the turtlebot).

We need odometry and would add the gyro also. Good odometry is necessary
and getting it just with encoders is very expensive.
