Returns a Boolean vector corresponding to the fixed elements of a permutation.
The function is vectorized; if given a vector of permutations,
fixed() returns a Boolean vector showing which elements are fixed
by all of the permutations.
This function has two methods: fixed.word() and
fixed.cycle(), neither of which coerce.
