New description:
Adds a method generating a permutation group's holomorph as a permutation
group.
The holomorph of a group is the semidirect product of itself with its
automorphism group, where the automorphism group acts canonically. This
method has been inserted into categories/groups.py with a
`NotImplementedError`, and then has been overridden in the case of
permutation groups.
