> The Drill RESTful interface does not return the structure of the query results.   This makes integrating Drill with other BI tools difficult because they do not know what kind of data to expect.  
> This PR adds a new section to the results called Metadata which contains a list of the minor types of all the columns returned.
> The query below will now return the following in the RESTful interface:
> {code:sql}
> SELECT CAST( employee_id AS INT) AS employee_id,
> full_name,
> first_name, 
> last_name, 
> CAST( position_id AS BIGINT) AS position_id, 
> position_title 
> FROM cp.`employee.json` LIMIT 2
> {code}
> {code}
