gotcha, it would be nice to match those units to ontology terms as well (when available).

For example:
> ```# TableCol  3 ColHeader SurfArea```
> ```# TableCol  3 FieldName Surface Area```
>``` # TableCol  3 Units     mm^2```

Would map to the term for square millimeter: http://purl.obolibrary.org/obo/UO_0000082
