The digest package provides an implementation of http.RoundTripper that takes
care of HTTP Digest Authentication (http://www.ietf.org/rfc/rfc2617.txt).
This only implements the MD5 and "auth" portions of the RFC, but that covers
the majority of avalible server side implementations including apache web
server.

Example usage

t := NewTransport("myUserName", "myP@55w0rd")
req, err := http.NewRequest("GET", "http://notreal.com/path?arg=1", nil)
if err != nil {
	return err
}
resp, err := t.RoundTrip(req)
if err != nil {
	return err
}

Or it can be used as a client:

c, err := t.Client()
if err != nil {
	return err
}
resp, err := c.Get("http://notreal.com/path?arg=1")
if err != nil {
	return err
}
