Detailed Description

stores a statistics about a set of addinfo objects.

The statistic objects provides information about the minimum and maximum value, as well as, the nummber of values that have been aggregated for each addinfo column. the minimum and maximum values can be accesed through two addinfo objects. It is secured that the minimum and maximum objects and the internal count vector are aligned (same AddInfoLayout)
