univariate gcd is performed using euclidean algorithm, which causes
explosion of coefficients and is slow but for trivial examples. Instead we
should use pari that performs better.
1.- Add a _pari_ function for absolute number fields taht work[[BR]]
2.- Add gcd using pari for absolute number fields[[BR]]
3.- For relative number fields, pass to an absolute representation. This
may be slow. But for the cases where this is slow the current
implementation may be unfeasible.
