[math] suggestion: introducing getSummary method on descriptive statistics

[Adriean Khisbe]

Hi, 
Working on a project I had to capture current state of a DescriptiveStatistics, 
and choosed to use a StatisticalSummaryValues to hold the value. 
I looked it if was possible to do it in one short method call, but didn't found 
the method.
However I found some equivalent in SummaryStatistics:
    /**     * Return a {@link StatisticalSummaryValues} instance reporting 
current     * statistics.     * @return Current values of statistics     */    
public StatisticalSummary getSummary() {        return new 
StatisticalSummaryValues(getMean(), getVariance(), getN(),                
getMax(), getMin(), getSum());    }
Might be a good thing to port this functionnality in DescriptiveStatistics so 
ones can do        recap.getSummary()instead of 
      new StatisticalSummaryValues(recap.getMean(), recap.getVariance(), 
recap.getN(),                    recap.getMax(), recap.getMin(), recap.getSum())
What do you think about this?

Regards :)
