    Example
    Create Composite Geographic Transformation
    // Create singleton from wkid
    CompositeGeographicTransformation cgt = 
        ArcGIS.Core.Geometry.CompositeGeographicTransformation.Create(108272);
    int count = cgt.Count;    // count = 1
    
    IList<GeographicTransformation> gts = cgt.Transformations 
                                    as IList<GeographicTransformation>;
    gts.Add(ArcGIS.Core.Geometry.GeographicTransformation.Create(1437, false));
    count = cgt.Count;        // count = 2
    
    // create from an enumeration
    CompositeGeographicTransformation another_cgt = 
                  ArcGIS.Core.Geometry.CompositeGeographicTransformation.Create(gts);
    GeographicTransformation gt0 = another_cgt[0];
    GeographicTransformation gt1 = another_cgt[1];
    
    // get the inverse
    CompositeGeographicTransformation inversed_cgt = another_cgt.GetInverse() as CompositeGeographicTransformation;
    // inversed_cgt[0] is same as gt1
    // inversed_cgt[1] is same as gt0
    
    var wkt = gt0.Wkt;
    // create from string 
    CompositeGeographicTransformation third_cgt = 
       ArcGIS.Core.Geometry.CompositeGeographicTransformation.Create(wkt, gt0.IsForward);
    count = third_cgt.Count;        // count = 1
    
    // create from josn
    string json = cgt.ToJson();
    CompositeGeographicTransformation joson_cgt = 
      DatumTransformation.CreateFromJson(json) as CompositeGeographicTransformation;
