I was looking to improve my HTML to Markdown conversion for a web
application I have, but it appears that after an npm install of breakdance
that importing the module causes a "TypeError: fs.readdirSync is not a function".

My suspicion is that it's because the breakdance CLI is part of the
module, even though it's not required if one is calling the
breakdance( html_text) function in a browser context.
