Initial work towards demonstration code and documentation

[d33bs]

This PR adds changes which are intended to demonstrate how to use Python code through Anaconda on UCB RC Alpine to a CU Anschutz audience. The majority of the content surrounds explaining what Alpine "is" and how to use the code from this repository to help them learn how to use it effectively for their research purposes.

Outside the scope of this PR and as a heads up just in case it changes the review somehow: I intend to reuse some of this content for a future set-website blog article surrounding the same topic. My feeling here was that someone may stumble across this information within Github directly (in a self-contained way) or may find it more appealing to read through the set-website blog. Generally open to the approach here.

Thanks in advance for any comments and suggestions you may have! Please don't hesitate to let me know if you have any questions.

I can't verify the accuracy of the Slurm and Alpine info, but everything here looks good. Cleanly explained and laid out. If I were needing to make use of Alpine, I think I could do it without problems following the instructions here.

Great work! I have no issues with the content itself; I think it's all good and quite valuable. I'm going to go ahead and approve it since we're on a bit of a tight deadline, but feel free to look at my comments and integrate them as you like.

That said, I don't know enough about the target audience quite yet to know what will make sense to them, what will go over their heads, and what they'll want to do that might be missing. IMHO, I think we should trial it with some people and keep this as a living document that we simplify or expand according to our test readers' feedback.

Thanks @vincerubinetti and @falquaddoomi for the great reviews and content suggestions! I think I've addressed all comments and will be merging this in.
