Merged Heather Ellsworth requested to merge heather.ellsworth/developer.puri.sm:introduction into master Oct 31, 2018

added more to the introduction paragraph (using Bob's words from #17 (closed))
added a stack picture
reduced the ToC so that only the top level is shown
moved the design section below the API docs since it's not what folks want to see first (Bob's point in #19)
