[robwandrews]

Port of tutorials from sandia labs develop branch.

I think we could shift this to 0.2 and release 0.1 of pvlib.

[wholmgren]

Agreed.

@Calama-Consulting ?

I changed the milestone to 0.2

[wholmgren]

I'm going to mark this 0.3 since I'm not sure what should be ported into new or existing notebooks and what should be put into the docstrings and sphinx documentation.

[wholmgren]

I've had a lot of offline feedback that broken tutorials a big problem and I'd like to do a 0.2.1 release with updated tutorials. I don't plan to make them read any better, just get them to the point that they can run end-to-end without exceptions. #69 is also relevant to this.

Will try to help here. My take on the Sphinx vs notebook issue is that personally I prefer a worked example to get up to speed first and then dig into the API-level docs. Trying to get into a new product just by reading the API docs is just too hard. So, let's fix the notebooks first.
