Drone

In order for the below test client and validators to work, we'll also need to
|
||||
spin up a drone to give out some test tokens. The drone delivers Milton
|
||||
Friedman-style "air drops" (free tokens to requesting clients) to be used in
|
||||
test transactions.
|

Start the drone on the leader node with:

```bash

$ ./multinode-demo/drone.sh
