title: How can I generate swagger based off of existing postman collection?
body: <p>I am developing a REST API. during development I have used postman (chrome extension) to use and document my API. It is a wonderful tool and I have most of my API endpoints in it. 
  However, as we near release I would like to document this API in swagger, how would I do that? Is there a way that I can generate swagger based off of the postman export?</p>
