title: How to use YELP API with OAuthSwift?
body: <p>I'm trying to use OAuthSwift with the Yelp API. One of the required parameters is requestTokenURL, authorizeURL, accessTokenURL; however, I already have the token itself from Yelp and there is no authorize URL for Yelp. Not including these parameters gives me an error. What is the correct way to use OAuthSwift with the Yelp API? Thank you.</p>
  
  <pre><code> func OAuthVerify(){
      let oauthswift = OAuth1Swift(
          consumerKey: "#",
          consumerSecret: "#",
          requestTokenUrl: "???",
          authorizeUrl:    "???",
          accessTokenUrl:  "???"
      )
      oauthswift.authorizeWithCallbackURL(NSURL(string: "oauth-swift://oauth-callback/")!, success: { (credential, response, parameters) -&gt; Void in
          self.grabYelpData(oauthswift,consumerKey: "RZKQlWV3nqdB-74fZZRQeg")
          }) { (error) -&gt; Void in
              print("error")
      }
  }
  
  func grabYelpData(oauthswift: OAuth1Swift, consumerKey: String){
      let url :String = "https://api.yelp.com/v2/search?"
      let parameters :Dictionary = [
          "term"           : "food",
          //"api_key"        : consumerKey,
          "location"       : "San Francisco",
      ]
      oauthswift.client.get(url, parameters: parameters,
          success: {
              data, response in
              let jsonDict: AnyObject! = try? NSJSONSerialization.JSONObjectWithData(data, options: [])
              print(jsonDict)
          }, failure: { error in
              print(error)
      })
  }
  </code></pre>
