I added autoSetMacs to the preferences of MiniEdit. It sets the MAC address to be equal to the host-part of the IP address, which is determined by the nodeNum option. This behaviour deviates from the standard Mininet behaviour that nodes get IP addresses and MAC addresses in the order that they are added. I can change this behaviour (let me know if you want me to do so), though I then would like to shoot in a different pull request changing both the IP and MAC address determination behaviour to be sequentially ordered by the hostname instead of the hidden nodeNum.
