      Description

      The CorrelateStream will compute the Pearsons correlation coefficient for two streams.

      Sample syntax below will calculate the Pearsons correlation for two time series streams. See SOLR-8963 for the time function:

      correlate(rollup(time(search()),
                rollup(time(search()))
