additionalAuthorizationParameters not exposed from Touch View Controller

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Need to add additional query string parameter to the authentication HTML URL 
request. The ability to add parameters exists in the GTMOAuth2SignIn class, 
however the view controller instantiates the signIn instance and therefore 
requires you to subclass the view controller in order to set 
additionalAuthorizationParameters on the sign in object.

This is for signing into LinkedIn; they require an additional 'state' query 
string parameter. https://developer.linkedin.com/documents/authentication

What is the expected output? What do you see instead?
Ability to affect the auth URL without having to subclass the OAuth2 web view 
controller.

What version of the product are you using? On what operating system?
iOS 6.1, bringing in the source via CocoaPods.

Please provide any additional information below.

Thanks,
Rene

Please close this issue. Didn't see the public signIn property on the OAuth2 
view controller. Apologies for the open issue.

Thanks,
Rene

Can you share your sample code - I couldn't get it to work.
