msgflo-cpp: C++ participant support for MsgFlo

MsgFlo is a distributed, polyglot FBP (flow-based-programming) runtime. It integrates with other FBP tools like the Flowhub visual programming IDE. This library makes it easy to create MsgFlo participants in C++.

msgflo-cpp is written in C++11 and is built on top of AMQP-CPP, libmosquitto and json11.

msgflo-cpp is primarily used on Embedded Linux, but should also be portable to other operating systems.

Status
