Original issue's description:
> Check in a simple pure-python based Markdown previewer.
>
> We are now trying to write more and more of our documentation
> as Markdown files that live in the repo, but there's no easy
> way to preview changes in a local checkout.
>
> This CL adds a simple previewing tool written in pure Python
> that depends on the 'Markdown' python package (also pure Python)
> to do all the heavy lifting. It aims to replicate the look
> and feel of googlesource.com as closely as possible.
