converting to random controller
new Random_controller implemented

For the duration of this test I am going to use a Random
controller.  This way I don't have to mess with any of the
sensor algorithms while I'm just working out the interface.
Besides I think it will be funny to watch Alfred run around
with a random input signal.
knocked out first two TODOs
updating to move back the desktop
Working demo of a fully OOP Arduino Robot Architecture

Functional demo with Sensors, Controller, Plant and Feedback.
Next is to to get the Random Controller integrated with
Alfred then move on to implementing the whisker controller.
