Create Jekyll template for doc site

[crandmck]

We need a JavaScript widget that essentially duplicates the navigation panel on http://docs.strongloop.com. The source of the nav content will be nested lists in markdown and the result at runtime should be a nice "expandable" navigation widget.

This is part of Proposal to make LoopBack documentation open source.

Big thumbs up! 👏

I found an excellent Jekyll theme that we should be able to leverage: http://idratherbewriting.com/documentation-theme-jekyll/ (source in https://github.com/tomjohnson1492/documentation-theme-jekyll). This has almost everything we need and is MIT-licensed.

Also, for comparison, this is very close to what we're looking for: http://hamishwillee.github.io/jekyll-bootstrap-docsite/ (source in https://github.com/hamishwillee/jekyll-bootstrap-docsite).

I'm going to close this, since we've chosen the documentation-theme-jekyll template and largely implemented it in http://loopback.io/doc/.
