oAuth and Yelp

Has anyone used the Yelp API and oAuth authentication?  This is new territory for me and would appreciate any assistance on getting passed the authentication phase.  Here’s the yelp doc: https://www.yelp.com/developers/documentation/v2/authentication

From what I’ve gathered I think I’d be able to use the oAuth.lua found in the Twitter sample project as this uses 1.0a.  Unfortunately this is all a bit over my head and not exactly sure how to pass tokens and what not.  

Any assistance is greatly appreciated.
