/**
 * [[InMemoryJSONEventBuffer]] is an in-memory implementation for buffering and
 * sending events. It buffers events based on number of events and its size whichever reaches
 * first. Events are sent out at an scheduled interval where important events are sent immediately.
 * It also retries sending events if failed upto the retry count limit. It implements
 * beaconing mechanism based on 'pagehide' and 'visibilitychange' to beacon all events as a last attempt.
