Overview

When registered as the notifier for a client it tracks the times for each part of the request. Rather than subclassing RFuzz::Notifier it uses a method_missing to record the even timings.

You can dump it with to_s, or you can access the StatsTracker.stats hash to read the RFuzz::Sampler objects related to each event.
