NeuronDotNet - Neural Networks in C#

Hi - Fantastic product. I am just starting out. I want to build a backprop network to do classificaton, like the example here:

http://en.wikiversity.org/wiki/Learning_and_Neural_Networks

I want to predict profession based on the data: Likes Star Trek and Good at Maths. Professions are Student, Engineer, Accoutant and Hairdresser.
So how do I set this up?

Do I need multiple outputs, one for each profession? How do I read multiple outputs?

Thanks in advance,

Matt
