 *
 *  Example 4: Genesis for NFT1 Parent - These are used to create individual NFT1 children
 *
 *  Instructions:
 *      (1) - Send some BCH to simpleledger:qrhvcy5xlegs858fjqf8ssl6a4f7wpstaqnt0wauwu
 *            or tBCH to slptest:qpwyc9jnwckntlpuslg7ncmhe2n423304ueqcyw80l
 *            to fund the example.
 *      (2) - Run `tsc && node <file-name.js>` just before script execution
 *      (3) - Optional: Use vscode debugger w/ launch.json settings
 *
