Lesson1 with Instagram search

[pivotal feature](https://www.pivotaltracker.com/story/show/69323762)
- Added a static html page to the public folder (didn't want to include the complex Codealia styling on this page)
- Used @Thomas's instagramBrowser JS library to populate static page with content

The problem now is that there is very little plain HTML left for students to remix and publish, each time the page is refreshed or 'Search' is clicked most of their X-Ray Goggles edits will be overwritten by the JS :(
