      Description

      DrillConvertletTable is used as a way to have custom functions. For example, for EXTRACT(), DrilLConvertletTable.get() returns DrillExtractConvertlet, which returns a custom RexNode for the extract function.

      On the other hand, DrillAvgVarianceConvertlet is never used. stddev/avg/variance functions are handled by DrillAggregateRule and DrillReduceAggregatesRule.
