Create a Codeigniter Soundcloud.com API Library

I am looking at creating a small mashup using the data stored on www.soundcloud.com. They offer an API, details here: [login to view URL] I need a Codeigniter library that gives me easy access to data sent back when doing a simple 'tracks' query for a user. Eg: [login to view URL] The data is returned as XML. I need to be able to access this data as simply as possible, perhaps as objects. The Codeigniter Library should work with the latest version of Codeigniter, and be a single .php file I can drop into my Libraries folder and call in the standard Codeigniter way. I would also like Documentation written using the standard Codeigniter template. eg: [login to view URL] I would like examples included in the documentation, including: How to access the data. How to loop through the data. If it helps you can find a PHP wrapper for the [login to view URL] library here: [login to view URL]
