Subject: - updated css, deployed readability on lab.arc90.com had some changes
 not included - added user font size and family styles to print css - added
 twitter link to index page and styles to css - updated readability-start.js
 to now use a dynamic lookup of the baseHref - added check for console object,
 creates blank object if not defined - this way we can hold onto the current
 debugging for now safely
