Using LithiumSSOClient

Hi,

I am trying to use the LIthiumSSOClient based on instructions here: http://community.lithium.com/t5/Community-API/bd-p/developers-rest-api?page=authentication#sso

I am not sure how I can leverage the Lithium client mentioned in the sample code:

 LithiumSSOClient ssoClient = LithiumSSOClient.getInstance(SSO_KEY.getRaw(), SSO_CLIENT_ID, SSO_CLIENT_DOMAIN,
           SSO_SERVER_ID);

How do I access the Lithium library which has this client?

thanks,

Karthik
