Concepts > Controllers: Add a section on how to access incoming request data

https://github.com/balderdashy/sails-docs/issues/934 --> Is still not resolved.

It would help to put the following statement on the sails controllers page:

// req.param will contain any route params, body params or
// query string params

Start with the Sails controllers documentation page and review the unresolved issue at balderdashy/sails-docs#934. Use the cited Stack Overflow question for context, then add a section explaining how incoming route, body, and query-string data are accessed through req.param. Done means the controller documentation clearly includes this guidance.
