NJ API for Cesium GeoMultiScreenWidget

Example:

HTML代码：

<div id="layout" style="position: relative;height: 100%;width: 100%;overflow:hidden;">
    <div id="leftContainer" style="position: absolute;width: 50%;border: 1px solid gray;height: 100%;left: 0;"></div>
    <div id="rightContainer" style="position: absolute;width: 50%;border: 1px solid gray;height: 100%;right: 0;"></div>
</div>

JavaScript代码：

 //创建多屏视图
 multiScreenWidget = new Cesium.GeoMultiScreenWidget({
     layoutId: "layout",
     viewers:[{
         {container:"leftContainer",options:{
             timeline: true
         }},
         {container:"rightContainer",options:{
             timeline: false
         }}
     }]
 });

 //加载图层
 var viewerleft = multiScreenWidget.getViewerById("leftContainer");

 });

 var tdt_img_layer = viewerleft.imageryLayers.addImageryProvider(tdt_img_provider);
 var tdt_img_note_layer = viewerleft.imageryLayers.addImageryProvider(tdt_img_note_provider);

 //加载图层

 });

 var tdt_vec_layer = viewerright.imageryLayers.addImageryProvider(tdt_vec_provider);
 var tdt_vec_note_layer = viewerright.imageryLayers.addImageryProvider(tdt_vec_note_provider);

 //定位
 viewerleft.camera.flyTo({
     destination: Cesium.Cartesian3.fromDegrees(114.31, 30.52, 500000.0)
