The functionality is probably best handled by a Stop-object.
Unfortunately, Gecode/J Gist does not accept Stop objects currently.
We'll see if it seems reasonable to do for the next release.

Otherwise, it shouldn't be too hard to add yourself.

I'm not sure if this is a generally useful feature, but it shouldn't
be to hard to do yourself. Essentially, what you would need is to add
a function to clear all saved copies from the tree apart from the root
node. Accessing any node would after this need to do a recomputation
from the root.

Cheers,
Mikael
