wold.pol can be used with three purposes:
(1) to transform a self-reciprocal or palindromic polynomial
a_0 + a_1(B+F) + a_2(B^2+F^2) + ... + a_p(B^p+F^p)
into a Wold polynomial
b_0 + b_1(B+F) + b_2(B+F)^2 + ... + b_p(B+F)^p;
(2) to revert the previous transformation to obtain the palindromic
polynominal from a Wold polynomial and
(3) to compute the Cramer-Wold factorization: b(B+F) = c(B)c(F).
