 It's useful when accepting Bitcoin to check the received Bitcoin on a specific address in your wallet.

 In BCRPC, you can generally use the same flags as in ```bitcoin-cli``` in BCRPC. Though you use camelCase (```getNewAddress```) for the methods, the flags, which are normally separated by spaces on the command line, are instead placed in strings and separated by commas.
