 /**
  * Generic Performance Event that can be used for performance measurements.
  * Customer measurements can be added to the bundle.
+ *
+ * Bundle is expected to have following properties:
+ * "attributes", "counters", and "metadata" with String values.
+ *
+ * Attributes: a string representing an array of name/string value pair objects.
+ * Counters: a string representing an array of name/number value pair objects.
+ * Metadata is a string representation of a JsonObject with string values.
+ *
+ *  Here is an example of a Performance event bundle data:
+ *
+ * "attributes": [{ "name": "style_id", "value": "mapbox://styles/mapbox/streets-v10"}]
+ *
+ * "counters": [{"name": "fps_average", "value": 90.7655486547093},
+ *              {"name": "fps_deviation", "value": 29.301809631465574}]
+ * “metadata”: {
+ *       “version”: “9”,
+ *       “screenSize”: “1080x1794”,
+ *       “country”: “US”,
