The start command
zallet start starts a Zallet wallet!
The command takes no arguments (beyond the top-level flags on zallet itself). When run,
Zallet will connect to the backing full node (which must be running), start syncing, and
begin listening for JSON-RPC connections.
You can shut down a running Zallet wallet with Ctrl+C if zallet is in the foreground,
or (on Unix systems) by sending it the signal SIGINT or SIGTERM.
