com.facebook.LinkBench.stats.SampledStats
This class is used to keep track of statistics. It collects a sample of the total data (controlled by maxsamples) and can then compute statistics based on that sample. The overall idea is to compute reasonably accurate statistics using bounded space. Currently the class is used to print out stats at given intervals, with the sample taken over a given time interval and printed at the end of the interval.
