--------------------------------

poly_hilbert_polynomial(I)
     :  It returns the Hilbert polynomial of the ideal I.

poly_hilbert_polynomial(I | S=key0,V=key1)
     : This function allows optional variables   S, V

   Description:

     The optional variable v is a list of variables.


   Example:
      poly_hilbert_polynomial([x1*y1,x1*y2,x2*y1,x2*y2]|s=k,v=[x1,x2,y1,y2]);
