This module encapsulates the raw interactions with Flickr's API - the creation of an HTTP request, signing of arguments, checking of response codes, and so forth.
End users shouldn't need to use this module - instead, use the Flickr::API2 object, and call 'execute_method' on it.
Constructor - takes arguments of: key (api key) secret (api key's secret) rest_uri (which URL at flickr to use - defaults to the correct value) auth_uri (which URL at flickr for authentication - defaults to correct value)
Signs the given arguments with the given secret key.
URI object representing the URL that an application must redirect a user to for approving an authentication token.
