First versions of full demo code

The arduino file has all the components I would ike to cover in the
class, and the processing file is as simple as possible while still
functioning as a controller. Further changes will be to set a specific
sequence when in "controlled mode"
Adding allSteps

This file is an outline of how to build up to the final product, one
piece at a time. Many of the steps are designed to error. Learning by
mistakes is good!
