- Moved navigation links view code from layouts/application.html.erb to shared/_nav_bar.html.erb.\n - Changed from layout through tables to layout through CSS and divs, spans.\n - Discovered and made use of new HTML elements: header, footer, main, nav, and section.  Section element allows linking to it rather than needing an anchor (a href='foo'), and better delineates the bounds of said section through its opening and closing tags.\n - Replaced generic 'Hello World' text on index page with a general description of services offered.
