La classe è stata modificata in Maggio 2009 da Giuseppe Labellarte
La classe viene chiamata con new Protoform('nome_form','opzioni relative ad ajax','par', 'par1'); 
opzioni relative ajax : {ajax: true} in caso non presente di default ajax è settato a true ed i
						 dati sono inviati con ajax;
par: {0,1,2}  0=lista puntata sotto il form(class error) - 1=lista puntata sotto form (errori_form_cell)
			   2=layer div posizionato vicino al campo errore (classe errore_alunni) 	
aggiunto campo Double per verificare un campo su funzione custom passata es: id="valida2()_Req_Double"
