 \brief Interface d'écriture des données d'une variable.
 
 Lors d'une écriture, l'ordre d'appel est le suivant:
 \code

 * writer->beginWrite(vars)
 * writer->setMetaData()
 * foreach(var in vars)
 *   writer->write(var,var_data)
 * writer->endWriter()
 \endcode
 \a vars contient la liste des variables qui vont être sauvées
