      Description

      StatsComponent - it returns min,max,sum,qt,avg of specified number fields:

      request parameters:
      &stats=on&stats.field=price

      <stats>
       <stats_fields>
         <lst name="price">
             <double name="min">10</double>
             <double name="max">30</double>
             <double name="avg">20</double>
             <double name="sum">60</double>
             <double name="qt">3</double>
         </lst>
       </stats_fields>
      </stats>
      

      WRT "stats", the component can output sum and avg, but not sd and var.

      USE CASE:
      StatsComponent can be used to get "market price" of DocSet e.g. rental housing site, package tour site.
