title: how to update network using composer install
body: <p>I am developing a nodejs client for a business network. I install the network version 100 . after I make some changes I redeployed it however the changes did not effect at least the nodejs client still logs it is connected to version 100. I increment the version 101 restart the nodejs still got 100 in the log. 
  what is the procedure to update the network?</p>
  
  <p>deploy command
  composer network deploy -a network.bna -p hlfv1 -i PeerAdmin -s anything</p>
  
  <p>oepn connection 
  this.bizNetworkConnection.connect(this.CONNECTION_PROFILE_NAME, this.businessNetworkIdentifier, participantId, participantPwd)</p>
  
  <p>log network identifier
  LOG.info('KYC:', 'businessNetworkDefinition obtained', this.businessNetworkDefinition.getIdentifier());</p>
