[Website]: Build microsite to show entire page views using components and styles

[joshbruce]

Description

@carlosvalle submitted a PR #79. This demonstrated a page layout for search results using straight-html and the SAMWDS. The output of this PR was demonstrated to @christyhermansen, @BrianGilmanGSA, and @tarandhupar. The idea listed out in the PR sounded like a good, and familiar, approach to all.

Proposal

• Create /_includes/documentation to house the includes for element and component pages.
• Move /_includes/elements and /_includes/components to /_includes/documentation.
• Create /_docs/microsite to establish permalink, metadata, page titles, and so on for microsite.
• Create /_includes/microsite to house HTML content - maintaining overall site pattern.
• Create /_templates/microsite-base.html to use a the base/default page template.
• Create /_docs/microsite/index.html to house the "home page" for the micro-site.

Did I miss anything?
