docs: OAuth workflow, step two: Get an authorization URL.
  <br>
  Once you have a request token pass it to this method to get the authorization URL.
  The user should be directed to the returned URL, where they can authorize your
  application. Once they have authorized your application, they will receive a
  verification code, which should be passed to the
  {@link #getAccessToken(org.scribe.model.Token, String)} method.
  
  @param requestToken the request token.
  @param permissions  the permissions your application is requesting.
  @return authorization URL that the user should be directed to.
  @throws JinxException if any parameter is null.
