<?php

/*
 * @file
 * This module provides a block with 2 links (Login, Register) for the anonymous user
 * When the user clicks on Login or register the requested form appears in a nice ajax popup
 * The login and register forms can validate using ajax and not redirect on error
 * On success the module redirects to the user page
 * When user is logged in, the block provides a Welcome !username message and a link to the user page
 * and a logout link.
