A mixin which adds the {@link VoxelInspector} widget to the {@link Viewer} widget.
Rather than being called directly, this function is normally passed as
a parameter to {@link Viewer#extend}, as shown in the example below.
@function

@param {Viewer} viewer The viewer instance.

@example
var viewer = new Cesium.Viewer('cesiumContainer');
viewer.extend(Cesium.viewerVoxelInspectorMixin);
