/**
 * Part of a course on Hyperledger Fabric: 
 * http://ACloudFan.com
 * 
 * Composer 0.20.5
 * Last Updated: Dec 21, 2018
 * 
 * Demostrates the use of factory received in the BN connection using
 * the getFactory( ) method to submit a transaction
 * 
 * Pre-Req
 * 1. Start the fabric
 * 2. Deploy & start airlinev7
 * 3. Start the REST Server
 *     
 *    composer-rest-server -c admin@airlinev7 -n never -u true -w true
 * 
 * 4. Make sure there is no Flight resource with id="AE101-05-12-2019"
 *    Delete it if you find one - Remember the code for CreateFlight
 *    Transaction has the flightId hardcoded :-)
 * 
 * Demo Steps
 * 1. Use the bn-connection-util to create the connection to airlinev7
 * 2. Get the Busines Network Definition from Runtime
 * 3. Get the factory from the Business Network definition
 * 4. Create a new Transaction instance
 * 5. Set the property values in the transaction object
 * 6. Submit the transaction

// 1. Connect to airlinev7
