I don't use SWIG myelf, but this looks like the examples in
examples/python/callback and callback2 in my installation.  It might
be a bit harder since you don't get to specify any data to the
callback, so you'd have no way of knowing which instance of GA_config
is being used, unless the Chrom_Ptr includes enough info.

Have you looked at these examples and gotten completely mystified, or
are you having trouble with another bit of this?
