Detailed Description

Class which provides a simple wheel (skid steering) odometry from asguard.

class is based on a simple skid steering model, where the change in orientation is provided by an IMU, so effectively only the translation comes from a change in wheel position.

Note: currently this class is specific to asguard, but can be made generic quite easily.
