New description:
Previously, when inserting a transition which is already present, this
was simply ignored. By providing a hook {{{on_duplicate_transition}}},
user
defined behaviour is now possible. As examples, three functions are
provided (the default ignore, maintaining the previous behaviour;
raise error or add input label). The latter may be used to model a
Markov chain where the input labels are interpreted als transition
probabilities.
