converted tabs to spaces, included option to parse out pageinfo from html, so if we wanted to include this module as part of a larger scraping operation, we could simply pass in the already-parsed html rather than making another request
dont need url for get_title
Merge pull request #1 from abelsonlive/master

Make it so `pageinfo` can accept raw html as an arg. This allows you to use `pageinfo` as a part of a larger scraping project without having to request a url twice.
