-/**
- * This class provides a simple interface for OpenID (1.1 and 2.0) authentication.
- * Supports Yadis discovery.
- * The authentication process is stateless/dumb.
- *
- * Usage:
- * Sign-on with OpenID is a two step process:
- * Step one is authentication with the provider:
- * <code>
- * $openid = new LightOpenID;
- * $openid->identity = 'ID supplied by user';
- * header('Location: ' . $openid->authUrl());
- * </code>
- * The provider then sends various parameters via GET, one of them is openid_mode.
- * Step two is verification:
- * <code>
- * if ($this->data['openid_mode']) {
- * $openid = new LightOpenID;
- * echo $openid->validate() ? 'Logged in.' : 'Failed';
- * }
- * </code>
- *
- * Optionally, you can set $returnUrl and $realm (or $trustRoot, which is an alias).
- * The default values for those are:
- * $openid->realm = (!empty($_SERVER['HTTPS']) ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'];
- * $openid->returnUrl = $openid->realm . $_SERVER['REQUEST_URI']; # without the query part, if present
- * If you don't know their meaning, refer to any openid tutorial, or specification. Or just guess.
- *
- * AX and SREG extensions are supported.
- * To use them, specify $openid->required and/or $openid->optional before calling $openid->authUrl().
- * These are arrays, with values being AX schema paths (the 'path' part of the URL).
- * For example:
- * $openid->required = array('namePerson/friendly', 'contact/email');
- * $openid->optional = array('namePerson/first');
- * If the server supports only SREG or OpenID 1.1, these are automaticaly
- * mapped to SREG names, so that user doesn't have to know anything about the server.
- *
- * To get the values, use $openid->getAttributes().
- *
- *
- * The library requires PHP >= 5.1.2 with curl or http/https stream wrappers enabled..
