Make / Brew / Build options for all lessons

[lwasser]

This issue is related to #4
where some interactive components don't render properly via jekyll. we might need to consider a local build option.

"You might consider opening a separate issue that tries to reconcile bringing these lessons together into a single site, factoring in this closed issue as a factor for consideration (if you want to include htmlwidgets) and one possibility to generate output (ie by skipping use of Jekyll and opting for simpler rendering methods like brew and Makefile)."
