Track notification listener

Description

The TRACK notification listener lets you implement additional functionality or system tracking on top of your instrumented Optimizely Track API calls. The Track method triggers this notification listener. Because Optimizely SDKs queue and batch events, there can be a delay between when the Track method captures an event, and when the event is actually sent to Optimizely as part of a batch. For more precise alignment with event batches, see the LOGEVENT notification listener.
