Example:
The example below publishes a message on the topic "/vx300/action".
The ~--once~ flag, specifies that the message should only be published once.
The message type is defined by "std_msgs/msg/String"
In this example, a string saying "place" is published. "data" is where the message is contained
This is useful for testing.
