    Represents an object to initialize with pre-defined properties such as renderer, visibility etc. for a sublayer and use that to create a SubtypeGroupLayer.

    Example
    Create a new SubTypeGroupLayer
    var subtypeGroupLayerCreateParam = new SubtypeGroupLayerCreationParams
    (
        new Uri(@"c:\data\SubtypeAndDomain.gdb\Fittings")
    );
    
    // Define Subtype layers
    //At 2.x - var rendererDefn1 = new UniqueValueRendererDefinition(new string[] { "type" });
    var rendererDefn1 = new UniqueValueRendererDefinition(new List<string> { "type" });
    var renderDefn2 = new SimpleRendererDefinition()
    {
      SymbolTemplate = SymbolFactory.Instance.ConstructPointSymbol(
              CIMColor.CreateRGBColor(255, 0, 0), 8, SimpleMarkerStyle.Hexagon).MakeSymbolReference()
    };
    subtypeGroupLayerCreateParam.SubtypeLayers = new List<SubtypeFeatureLayerCreationParams>()
    {
      //define first subtype layer with unique value renderer
      //At 2.x - new SubtypeFeatureLayerCreationParams(new UniqueValueRendererDefinition(new string[] { "type" }), 1),
      new SubtypeFeatureLayerCreationParams(new UniqueValueRendererDefinition(new List<string> { "type" }), 1),
    
      //define second subtype layer with simple symbol renderer
      new SubtypeFeatureLayerCreationParams(renderDefn2, 2)
    };
    
    // Define additional parameters
    //At - 2.x subtypeGroupLayerCreateParam.DefinitionFilter = new CIMDefinitionFilter()
    //{
    //  Name = "IsActive",
    //  DefinitionExpression = "Enabled = 1"
    //};
    subtypeGroupLayerCreateParam.DefinitionQuery = new DefinitionQuery(whereClause: "Enabled = 1", name: "IsActive");
    subtypeGroupLayerCreateParam.IsVisible = true;
    subtypeGroupLayerCreateParam.MinimumScale = 50000;
    
    SubtypeGroupLayer subtypeGroupLayer2 = LayerFactory.Instance.CreateLayer<SubtypeGroupLayer>(
                  subtypeGroupLayerCreateParam, MapView.Active.Map);
