Lightweight internet bridge.
Created with OpenComputers in mind and goes with Lua API library.
This is C++ library to connect to stem servers and send/receive data.
stemlib::Client class automatically manages its subscriptions and makes sure traffic is not eaten by some obscure channel that no stemlib::Listener listens to it and makes easy using multiple stemlib::Listeners with one client, which lowers traffic usage even lower if you have high data throughput application.
(Uses Poco::Net)
