1) Created an app within mezzanine-themes to start building "coworker" theme by gradually overriding the "business" template.
2) Created defaults.py file to allow overriding default setting values.
3) Purchased "coworker" template (http://themeforest.net/item/coworker-responsive-multipurpose-template/3981356)
4) Copied all of the purchased coworker template to /mezzanine_themes/coworker/static/purchased_template
