title: Flask-RESTPlus - How to get query arguments?
body: <p>I'm curious how I can take query arguments coming from the GET method in Flask-RESTPlus. I didn't managed to find an example in the documentation. </p>
  
  <p>I have previously used pure flask and the way I was doing it was by calling 'request.args.get()' from the flask library. Any ideas how to achieve this in RESTPlus?</p>
