Note: Only one of the phpCAS::client() and phpCAS::proxy functions should be called, only once, and before all other methods (except phpCAS::getVersion() and phpCAS::setDebug()).

Parameters

$server_version	the version of the CAS server
$server_hostname	the hostname of the CAS server
$server_port	the port the CAS server is running on
$server_uri	the URI the CAS server is responding on
$start_session	Have phpCAS start PHP sessions (default true)

Returns: a newly created CASClient object
