# Demo to use configtxlator to add some new organization
# Usage:
# Configtxlator APIs:
	# Json -> ProtoBuf: http://$SERVER:$PORT/protolator/encode/<message.Name>
	# ProtoBuf -> Json: http://$SERVER:$PORT/protolator/decode/<message.Name>
	# Compute Update: http://$SERVER:$PORT/configtxlator/compute/update-from-configs
# <message.Name> could be: common.Block, common.Envelope, common.ConfigEnvelope, common.ConfigUpdateEnvelope, common.Config, common.ConfigUpdate
# More details about configtxlator, see http://hlf.readthedocs.io/en/latest/configtxlator.html
