Represents a row of a report.

NOTE: The [SearchRow](https://developers.google.com/google-ads/scripts/docs/reference/adsapp/adsapp_searchrow) is a JavaScript
Object, holding all values requested. These values are nested inside the row
object.

Typical usage:

```
  var query = 'SELECT campaign.id, campaign.name FROM campaign';
  var rows = AdsApp.search(query);
  while (rows.hasNext()) {
    var row = rows.next();
    // The row works as an associative array
    var campaign = row.campaign;
    var id = campaign.id;
    var name = campaign.name;
  }
```
