    Courses#index works.

    But an issues with express-resource has been uncovered; it doesn't parse
    Accept: headers but only relies on *.<format> -- which is a kinda poor
    way of supporting content negotation. Express comes with `req.accepts()`
    and `req.accepted` which are appropriate.
