Title: Add image tutorial as ipynb - with some additional content

Preliminary folder at root level called "tutorials" - probably not exactly what you guys want, but just a proposal to get the discussion going on where IPython Notebook-based tutorials might live.

The additional content is regarding axes calibration (extent) and aspect ratio. There's also a little bit of cleanup/rework.
