ROS Pololu driver

I will write a ROS wrapper for the Pololu MinIMU-9 v2 (L3GD20 and LSM303DLHC Carrier). More info inside.

The Pololu MinIMU-9 v2 comes with a driver for reading data in serial from the L3GD20 accelerometer and gyroscope, and the LSM303DLHC magnetometer. There is a whole range of products these drivers work with, but the ROS driver/bridge will only be tested for the MinIMU9 v2. My primary need is for the L3GD20 to work, so the focus will be on that for now.

This work will be in my pololu_imu ROS package. It will depend on rosserial and rosserial_arduino.
