The documentation for idealappr(K,P) implies that in the case that P a
prime ideal in the number field K, the element returned will be a
uniformizer for P and integral.
Will it always be a generator for P when P is principal (as it might
then be), or might the function return some other uniformizer?
If the latter, would it be relatively expensive to call
bnfisprincipal() to ensure that we have a generator when it exists?
