This example application demonstrates how to do simple playback and authentication with the Rdio iOS SDK.
To use this, you'll need to head over to https://rdio.com/developers/, create an OAuth 2.0 application,
and put your client_id and client_secret into Hello/ClientCredentials.h.
See Hello/ClientCredentials_EXAMPLE.h
for an example of what that file should look like.
A more advanced example is coming soon.
