example sub directoryThe example sub-directory has utilities classes to make the example simpler, these classes are not directly related to the use of proton so are in a separate `example` directory and namespace.Connects to a broker on 127.0.0.1:5672, establishes a subscription from the 'examples' node, and creates a sending link to the same node. Sends one message and receives it back.
