/**
* A feature of a [Cesium3DTileset].
*
* Provides access to a feature's properties stored in the tile's batch table, as well
* as the ability to show/hide a feature and change its highlight color via
* [Cesium3DTileFeature.show] and [Cesium3DTileFeature.color], respectively.
*
* Modifications to a `Cesium3DTileFeature` object have the lifetime of the tile's
* content. If the tile's content is unloaded, e.g., due to it going out of view and needing
* to free space in the cache for visible tiles, listen to the [Cesium3DTileset.tileUnload] event to save any
* modifications. Also listen to the [Cesium3DTileset.tileVisible] event to reapply any modifications.
*
* Do not construct this directly. Access it through [Cesium3DTileContent.getFeature]
* or picking using [Scene.pick].
* ```
* // On mouse over, display all the properties for a feature in the console log.
* handler.setInputAction(function(movement) {
* var feature = scene.pick(movement.endPosition);
* if (feature instanceof Cesium3DTileFeature) {
* var propertyNames = feature.getPropertyNames();
* var length = propertyNames.length;
* for (var i = 0; i < length; ++i) {
* var propertyName = propertyNames[i];
* console.log(propertyName + ': ' + feature.getProperty(propertyName));
* }
* }
* }, ScreenSpaceEventType.MOUSE_MOVE);
