/**
 * Implementation of
 * {@link org.apache.commons.math.stat.descriptive.SummaryStatistics} that
 * is safe to use in a multithreaded environment.  Multiple threads can safely
 * operate on a single instance without causing runtime exceptions due to race
 * conditions.  In effect, this implementation makes modification and access
 * methods atomic operations for a single instance.  That is to say, as one
 * thread is computing a statistic from the instance, no other thread can modify
 * the instance nor compute another statistic. 
 *
 * @since 1.2
