Using Adafruit16CServoDriver in Myrobotlab

A demo of using the Adafruit16CServoDriver in MyRobotlab directly on the GPIO pins of a Raspberry PI. This is work in progress. The intension is to make a simple i2c interface available to be used either directly off the RaspBerry PI or using an Arduinos i2c pins. Now I have a set of methods to read and write i2c commands thr the RasPi service. NExt step is to implement the same methods in the Arduino service and pass the read/write commands to the Ardino. After that we can build i2c devices and not worry about learnin/building separate librarys for the Arduino or Raspberry. However it will take a little more effort to understand each device, and implement that parts that normally belongs to a device library in the drivers.
