// Calcola la distanza tra punto e superficie bezier.
// Risultati :
// - distanza
// - punto sulla superficie a minima distanza
// - corrispettivo punto nello spazio parametrico
// - normale alla superficie in quel punto
// - indicazione se il punto di riferimento è dalla parte interna o esterna della superficie ( se chiusa ).
// - indicazione se il punto di riferimento è a destra o sinistra della superficie ( se aperta )
