 /**
  * Fetch a Kolab object.
  *
  * This method will not retrieve any data from the server
  * immediately. Instead it will simply generate a new instance for the
  * desired object.
  *
  * The server data will only be accessed once you start reading the object
  * data.
  *
  * This method can also be used in order to fetch non-existing objects that
  * will be saved later. This is however not recommended and you should
  * rather use the add($info) method for that.
  *
  * If you do not provide the object type the server will try to determine it
  * automatically based on the uid. As this requires reading data from the
  * server it is recommended to specify the object type whenever it is known.
  *
  * If you do not specify a uid the object corresponding to the user bound to
  * the server will be returned.
  *
  * @param string $guid The GUID of the object to fetch.
  * @param string $type The type of the object to fetch.
  *
  * @return Kolab_Object The corresponding Kolab object.
  *
  * @throws Horde_Kolab_Server_Exception
