Introduction

Hallo everyone, 

I have added an introduction notebook with some stuff for the first 30 minute bit. This is still WIP - a couple of more elaborate examples will come towards the end - but et me know if you have any comments.

A general suggestion is to rename the notebooks so that they get ordered in the right order in the notebook directory, by adding a %3d number in the beginning of the file-name. What do y'all think?
