public TabellaIntorni(java.lang.String nomeFile)
Legge una neighborhood table da file.
Il file e' organizzato come segue: 
 term1
         term1,1 , w1,1
         term1,2 , w1,2
         ...
         term1,N1 , w1,N1
 ...
 termM
         termM,1 , wM,1
         ...
         termM,NM , wM,NM
Il termI,J e' nell'intorno di termI con peso wI,J.

I terminiI iniziano alla prima colonna.
Le righe contenenti i terminiI,J iniziano con un carattere di tabulazione.
Le linee che iniziano con # sono scartate.

Si assume che i termini siano stati gia' normalizzati.
