first drafts of some classes. I currently have no hardware to test the code, but it compiles in a test environment
fixed some typos
clarified branch model
implement simple tool to generate random answer sets
add DEBUG define to build a special debugging release
new method to show the result state of an answer
remove not yet finished class before merge
First implementation of the basic classes.
The classes are tested in isolated Arduino projects. I can't figure out how to embed these test project into my project for now.
