---------------------------

             Summary: DescriptiveStatistics return geometric mean as 0 when 
product of values is zero, expected to return NaN

        public void test() {
                DescriptiveStatistics stats = new DescriptiveStatistics();
                stats.addValue(1);
                stats.addValue(2);
                stats.addValue(4);
                System.out.println(stats.getGeometricMean()); //prints 2
                stats.addValue(0);
                System.out.println(stats.getGeometricMean()); //prints 0,
