class PolynomialXY : public Polynomial
/*
   This class implements a polynomial with two variables X and Y.
 DESCRIPTION :
   The coefficients a_i of a polynomial are stored in the following sequence:
				   2                2       3
   p(X,Y) = a1 + a2 X + a3 Y + a4 X  + a5 X Y + a6 Y  + a7 X  + ...
 REMARK :
   The degree of such polynomial is temporarily limited to 1 ; it can be
   easily increased whenever required.
