The IMU stick will use a submodule written for the sensor stick.

The robotics fork will allow us to modify the code to work with ros
and will make it easier for us to customize the software slightly.

The localization package will contain code to help find the robots
position.  It currently houses the orientation node which is empty and
simply spins forever while ros is running.

A custom message has also been added which represents the euler angle
orientation of the robot and has three components: yaw, pitch and roll.

The submodule was update to use a custom message from localization.

A node was created that recieves messages from the imu and publishes
the corresponding information as a quaternion.
