 * @param array $args
 *   An associative array whose keys are the methods to call and whose values

 * @param array $headers
 *   (optional) An array of headers to pass along.

 *   For one request:

 *     If FALSE is returned, see xmlrpc_errno() and xmlrpc_error_msg().
 *   For multiple requests:
 *     An array of results. Each result will either be the result
 *     returned by the method called, or an xmlrpc_error object if the call
 *     failed. See xmlrpc_error().
