Variance and standard deviation of process wait times with CPUSS
Getting the variance and standard deviation of process wait times over the course of the simulation is really simple, it's simply a call to a few methods.
Note: in CPUSS 0.7 there will be overloads for GetVariance and GetStandardDeviation that accept a predicate function so you can get the stats on specific processes.
