code: function(bin, full) {
        var url = [];
  
        if (bin.url) {
          url.push(bin.url);
  
          if (bin.revision) {
            url.push(bin.revision);
          }
        }
  
        return this.url(url.join('/'), full);
      }
docs: Same as helper.url() but creates a url for the bin object provided.
