Evaluators
                 Key: SOLR-10696
                 URL: https://issues.apache.org/jira/browse/SOLR-10696
             Project: Solr
          Issue Type: New Feature
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Joel Bernstein


The *empirical distribution* Stream Evaluator loads an array and creates a 
distribution based only on the underlying data. It returns summary stats for 
the distribution.

The *percentile* Stream Evaluator returns the percentile of a number for a 
specific empirical distribution. 

Syntax:
{code}
e = empiricalDistribution(colA)
p = percentile(e, 23)
{code}
