/*
The default response is a JSON object containing two members:

	api_version contains the version of the API responding (positive integer)
	auth whether the request was successfully authenticated (boolean integer)

The API can also return XML by passing xml as the optional value of the api argument like so:

http://yourdomain.com/fever/?api=xml

The top level XML element is named response.

The response to each successfully authenticated request will have auth set to 1 and include
at least one additional member:

	last_refreshed_on_time contains the time of the most recently refreshed (not updated)
	feed (Unix timestamp/integer)
