/**
* __call Catchall. This method catches remote method calls and provides for remote forwarding.
*
* If the parameters are native types, this method will use XML_RPC_Value::createFromNative to
* convert it into an XML-RPC type. Whenever a parameter is already an instance of XML_RPC_Value
* it will be used as provided. It follows that, in situations when XML_RPC_Value::createFromNative
* proves inacurate -- as when encoding DateTime values -- you should present an instance of
* XML_RPC_Value in lieu of the native parameter.
*
* @param string Method name
* @param array Parameters
* @return mixed The call result, already decoded into native types
