A base class for dispatching analytics events on a dedicated thread.
This class is particularly useful for sending analytics events to a web
server without blocking the message thread. It can also save (and restore)
events that were not dispatched so no information is lost when an internet
connection is absent or something else prevents successful logging.
Once startAnalyticsThread is called the logBatchedEvents method is
periodically invoked on an analytics thread, with the period determined by
calls to setBatchPeriod. Here events are grouped together into batches, with
the maximum batch size set by the implementation of getMaximumBatchSize.
It's important to call stopAnalyticsThread in the destructor of your
subclass (or before then) to give the analytics thread time to shut down.
Calling stopAnalyticsThread will, in turn, call stopLoggingEvents, which
you should use to terminate the currently running logBatchedEvents call.
