- Extend the multipart API to allow sending vectors of messages or helper
thin wrapper FairMQParts. See example in examples/MQ/8-multipart.
- NewMessage() can be used in devices instead of
fTransportFactory->CreateMessage().
Possible arguments remain unchanged (no args, size or data+size).
- Send()/Receive() methods can be used in devices instead of
fChannels.at("chan").at(i).Send()/Receive():
Send(msg, "chan", i = 0), Receive(msg, "chan", i = 0).
- Use the new methods in MQ examples and tests.
- No breaking changes, but FAIRMQ_INTERFACE_VERSION is incremented to 3
to allow to check for new methods.

Example 6: Multiple Channels
This example demonstrates how to work with multiple channels and multiplex between them.
A topology of three devices - Sampler, Sink and Broadcaster. The Sampler sends data to the Sink via the PUSH-PULL pattern. The Broadcaster device sends a message to both Sampler and Sink containing a string "OK" every second. The Broadcaster sends the message via PUB pattern. Both Sampler and Sink, besides doing their PUSH-PULL job, listen via SUB to the Broadcaster.
The multiplexing between their data channels and the broadcast channels happens with FairMQPoller.
