oAuth without `accessToken` and `secretToken`

[zoran119]

Is it possible to do oAuth authentication without accessToken and secretToken using HTTP Builder?

It seems to me that signpost allows it (see constructor for DefaultOAuthConsumer at http://mttkay.github.io/signpost/signpost-core-apidocs/index.html). It only takes consumerKey and consumerSecret:

DefaultOAuthConsumer(String consumerKey, String consumerSecret)

Or am I missing the point here...
