 * This function will take an aggregated collection of Summary Statistics
 * and will generate a derived {@link SummaryStatistic} based on a flag for the  
 * desired summation.  This is particularly helpful for finding out the
 * means of the individual statistics of the collection.
 * For example, if you wanted to find out the mean of means of the collection
 * you would call this function like <p>
 * getSummaryStatisticsForCollection(aggregate,1).getMean(); <p>
 * Or if you wanted to determine the max number of annotations per
 * individual, you could call: <p>
 * getSummaryStatisticsForCollection(aggregate,5).getMax(); <p>
 * The stat flag should be set to the particular individual statistic that should
 * be summarized over.
 *
 * @param aggregate The aggregated collection of summary statistics
 * @param stat  Integer flag for the statistic (1:mean ; 2:sum; 3:min; 4:max; 5:N)
 * @return {@link SummaryStatistics} of the selected statistic
