Added a new option for creating channel: Running ./network.sh createChannel -bft will initiate a channel running BFT orderers. Using ./network.sh up -bft will initiate dockers for bft environment. Added option for 4 orderers. Add add_new_orderer_to_config.py which is referenced in the fabric official docs.
