    Example
    Create a new spatial map series
    // This example create a new spatial map series and then applies it to the active layout. This will automatically 
    // overwrite an existing map series if one is already present.
    
    //Reference map frame and index layer
    MapFrame mf = layout.FindElement("Map Frame") as MapFrame;
    Map m = mf.Map;
    BasicFeatureLayer indexLyr = m.FindLayers("Countries").FirstOrDefault() as BasicFeatureLayer;
    
    //Construct map series on worker thread
    await QueuedTask.Run(() =>
    {
      //SpatialMapSeries constructor - required parameters
      SpatialMapSeries SMS = MapSeries.CreateSpatialMapSeries(layout, mf, indexLyr, "Name");
      
      //Set optional, non-default values
      SMS.CategoryField = "Continent";
      SMS.SortField = "Population";
      SMS.ExtentOptions = ExtentFitType.BestFit;
      SMS.MarginType = ArcGIS.Core.CIM.UnitType.PageUnits;
      SMS.MarginUnits = ArcGIS.Core.Geometry.LinearUnit.Centimeters;
      SMS.Margin = 1;
      SMS.ScaleRounding = 1000;
      layout.SetMapSeries(SMS);  //Overwrite existing map series.
    });
