History
Alexey Rybalchenko 7ab6afa28a Remove compile time transport interface switch 
- Remove the compile time check of the transport implementation.
  The transport (zeromq/nanomsg) can be chosen at run time with:
  `device.SetTransport("zeromq"); // possible values are "zeromq" and "nanomsg"`.

  For devices that use FairMQProgOptions, the transport can be configured via cmd option:
  `--transport zeromq` or `--transport nanomsg`. Default values is "zeromq".
  The device receives the configured value with:
  `device.SetTransport(config.GetValue<std::string>("transport"));`

  Old method of setting transport still works. But the NANOMSG constant is not defined.

- Remove old `fairmq/prototest` directory. It was only used as a test for protobuf.
  The protobuf part of Tutorial3 does the same (with different values).

- Fix a bug in FairMQPollerNN, where the `revents` value was not initialized.
  This caused the `poller->CheckOutput()` to trigger when it should not.

Example 1: Sampler -> Sink

A simple topology of two devices - Sampler and Sink. Sampler sends data to Sink via the PUSH-PULL pattern.

runExample1Sampler.cxx and runExample1Sink.cxx configure and run the devices in their main function.

The executables take two required command line parameters: --id and --config-json-file. The value of --id should be a unique identifier and the value for --config-json-file a path to a config file. The config file for this example is ex1-sampler-sink.json and it contains configuration for the communication channels of the devices. The mapping between a specific device and the configuration (which can contain multiple devices) is done based on the id.
