 Utilisation :



	1 - Construction

			 itemToCheck(

				identifiant du champ [Object],  

				not null [boolean],

				type de format attendu [string: 'email', 'string' ...],

				longueur mini attendue [integer (-1 pour desactiver)],

				langueur max attendue [integer (-1 pour desactiver)],

				Label du champ utilise lors de l'affichage de message d'erreur

				)

	2 - Creation de date a partir de 3 champs (jour/mois/annee)

			createDate(

				identifiant du champ Day,

				identifiant du champ Month,

				identifiant du champ Year,

				Separateur a utiliser entre les champs

				Type de date (us/fr)

				)

				

	3 - Verification de la validite

			Check() return true/false
