Update

I've let things go too long without any update so here it goes. Progress was really slow for a while (there wasn't any) as I was very busy with school. I have graduated now and in between job hunting I have been finally getting some work done on the project. I have re-organized the classes by moving the Worker class into the main Gnubert class and renaming GnubertTools to GnubertClient. It could probably still use a bit more polishing but I hope this makes things a bit more readable. I have also added an immigrant queue which is maintained by GnubertClient (now a separate thread.) so that the evolution process no longer has to wait for an immigrant to be obtained from other clients.
