prefers
Determines which content-types the client prefers. If no parameters are given,
the single content-type that the client most likely prefers is returned. If $type is
an array, the first item in the array that the client accepts is returned.
Preference is determined primarily by the file extension parsed by the Router
if provided, and secondarily by the list of content-types provided in
HTTP_ACCEPT.
