Updated README.  Had gotten out of sync with where I actually am.
added heading to &lt;nav&gt; and &lt;aside&gt;s, implemented &lt;figure&gt; tags

&lt;figure&gt; tags introduce their default styling, lots of work
trying to retain the original layout.
Week of 2/7 - 2/13.  New Gallery index.

Also committing lesson_02.* as they show uncommitted.  Write-up of
Gallery update in lesson-03/README.md
