Add ability to parse .sql files like views

[vitodcampanelli]

I would like to be able to create documentation for views as well.
It would be nice if it would be able to get the fields from the select list or the ability to add the fields manually.
I tried to use the template package.md for .sql but all that display is the description.
I would like to be able to do something like this:

/**
 * View is used for ..........
 *
 * @field field1 maybe ability to description of field
 * @field field2 maybe ability to description of field
 *
 * @author John Doe
 * @created 23-Nov-2017
 */

Thanks
