/**
 * CreateAndShareModule
 * @author Jae Cho
 *
 * Singleton class for interacting with Create and Share Flash game for login/register.
 *
 * Create and share requires a user to login to save the game data. When user clicks on
 * save button from the game, the following happens:
 *
 * 1. if user is logged in, user id is passed to the game.
 * 2. if user is logged out, the login dialog pops up
 *  a. if user logs in, the uid is passed to the game
 *  b. if user registers, the new uid is passed to the game
 *  c. if user does not login, cancel event is passed to the game.
