assertion types can provide callbacks

Submitted on request for Issue #20

[bploetz]

Can you please also add a note about this feature (with an example) in the README?

[pacovell]

Sorry, behind on this -- here is my example, for @edgar in the other issue:

In application.rb or other initializer with scope to config.oauth:

config.oauth.assertion_handler['facebook.com'] = lambda do |client, assertion, scope|
  Rails.logger.debug("Assertion: #{assertion}")
  graph = Koala::Facebook::GraphAPI.new(assertion)
  begin
    user_data = graph.get_object('me')
    Rails.logger.debug("FB User Data: #{user_data}")
    user = User.find_by_facebook_auth({ :uid => user_data['id']})
  rescue Exception => e
    # fall through
    Rails.logger.debug("Could not find/load Facebook user: #{assertion} / #{e}")
  end
  if user
    Rails.logger.debug('Valid Facebook Assertion')
    user.id.to_s # Requires a string or integer
  else
    Rails.logger.debug('Invalid Facebook Assertion')
    nil
  end
end

If you want this to be called, then your client needs to send its assertion like this (JSON format here):

{
  client_id: <apiClientId>,
  client_secret: <apiClientSecret>,
  grant_type: 'assertion',
  assertion_type: 'facebook.com',
  assertion: <fb access token>
}

@pacovell can you add this example and info to the README? Note that I just did a release, so if you could rebase your branch on top of master that would be great.

[pacovell]

OK, rebased, README updated, and made a new pull request.

Thanks,
-Paul
