This is what I ended up doing. At first I was motivated to have
a single method to define transitions (I thought this made the interface
easier to understand). Then I decided to change the internal representation
to have two dictionaries. This made the internal logic easier. 
Then I decided to split the interface and have two methods --
one for defining regular transitions and one for special transitions
and I think this made the interface more clear too; although, at the
expense of a slightly more complex interface.

Yours,
Noah
