So I have to call the function first? ;/ Isn't going to work ;/ I have to
get the probabilities from the function to determine which function to call
;/
Ultimately it seems I'm going to have to use functors or just write a method
to add the functions that takes a pointer but just seems a little overkill
just to add one "attribute".
