    ///       Newtonsoft.Json.dll
    ///       System.Net.Http.dll
    ///       System.Net.Http.Formatting.dll
    ///       System.Net.Http.WebRequest.dll
    ///       System.Web.Http.WebHost.dll
    
    ///       Go into Site Manager and exclude the URL to your /api path. There is *no* actual /api folder 
    ///       in the file system, and you don't want Kentico trying to rewrite it.
    
    ///       After you make the changes below, you can add a controller anywhere in your App_Code folder.
    ///       I created a Controllers folder underneath App_Code, then added a New Item > Web API Controller.
