> This JIRA is for computing the Pearson linear correlation for two numerical columns in a DataFrame. The method `corr` should live under `df.stat`:
> {code}
> df.stat.corr(col1, col2, method="pearson"): Double
> {code}
> `method` will be used when we add other correlations.
> Similar to SPARK-7240, UDAF will be added later.
