SimpleExtraction (druid-sql 0.12.3 API)

```
public class SimpleExtraction
extends Object
```
Represents a "simple" extraction of a value from a Druid row, which is defined as a column plus an extractionFn. This is useful since identifying simple extractions and treating them specially can allow Druid to perform additional optimizations.
