title: Add a header parameter in Swagger UI documentation with Springfox
body: <p>I want to add a header parameter field in the auto-generated swagger ui documentation of my rest service. I use Spring and Springfox.</p>
  
  <pre><code>public ResponseEntity&lt;User&gt; saveNewUser(
          @ApiParam(value = "the user to create", required = true) @RequestBody User user) throws RestServiceException {
  
      userService.save(user);
      return new ResponseEntity&lt;User&gt;(user, HttpStatus.OK);
  }
  </code></pre>
  
  <p>As you see I have already a <strong>body</strong> type parameter. I just want to add a <strong>header</strong> type one.</p>
