+ * [t send:[[[GAIDictionaryBuilder createEventWithCategory:@"EventCategory"
+ *                                                  action:@"EventAction"

+ * This will send an event hit type with the specified parameters
+ * and a custom dimension parameter.
+ * <br>
+ * If you want to send a parameter with all hits, set it on GAITracker directly.
+ * <code>
