- Rename Tutorial3 MQ files for uniform naming. - Add search for dylib in FindDDS.cmake (OSX). - Add more detail to the DDS example readme. - MQ Example 3 (DDS): choose network interface via command line option. - Give FairMQ examples their own CMakeLists.txt for clarity. - Remove C++11 checks in Tutorial3 from the code (they are now in CMake). - Add Serializer for device properties (FairMQDevice::ListProperties()).
