Minor bug note:
The goal-to-target connections only briefly mentioned in this paper should be ignored.
The mechanism for this was broken. Thankfully, this was irrelevant for the published
data, but if you use this particular version of the model, then you should not use
the goalTarg array in Main.java. In the case that goalDec and goalTarg are identical
(as was the case in the published data), the goalTarg array is irrelevant. In the case
that the two happen to be different, use of the goalTarg array could lead to
undesirable behaviour. Note that this array has simply been removed from the
subsequent version of the model.
