      Description

      This patch adds more statistics to the ConfusionMatrix and RequestAnalyzer.

      1. Add Kappa measure - a standard measure comparing a sample v.s. random assignment.
      2. Add mean & standard deviation of "Reliability" (User Accuracy) - assist in identifying consistent mal-assignment against "good" and "bad" labels.
