// CreateAndLogin does the following:
//
// - Search for an existing user - session -> Profile -> email address
// - Saves the Profile to the datastore
// - Creates a User or appends the AuthID to the Requesting user's account
// - Logs in the User
// - Adds the admin role to the User if they are an GAE Admin.
