-						 un punto fuori.
-						 Tolto un Normalize inutile
- 2001 May 17 Aggiunta versione della Mindistpoint che da anche le coord 
-						 baricentriche del punto trovato (pc); aggiunto wrapper per la vecchia 
-						 versione.
-			Dec 10 Corretto prodotto scalare vettore nell'ordine giusto in un paio di posti
- 2002 Mar 29 Templatata anche in funzione del tipo scalare. (pc)
-      Oct 24 Corretti warning (unsigned mismatch) del vc7, 
- 2003 Apr 15 Corretti mismatch iterator / pointer 
-      Jun 08 Aggiornato UGridLink -> UGrid::Link
