Here you go, its best to put them in a large sim(10) against a little ammount of bots at the start so they can develop.
One of the bug with it is when young ones are born, they either connect to eachother or connect backwards down the branches so they are connected to eachother. Another problem is getting the "seeds" to deattach from the tree and start a new tree elsewhere but...
Hope you enjoy it.
