A very simple signal/slot library for C++11.
Just copy signal11.h in your project.
You probably need to enable the C++11 mode of your compiler, clang++ and g++ use -std=c++11.
signal11<A, B, C> signal;
Declares a signal taking three arguments of types A, B and C.
There is no limit on the amount of arguments.
signal.connect(function);
Connects function (anything accepted by std::function<void(A, B, C)>) to the signal.
function(a, b, c) will be called anytime signal(a, b, c) is called.
auto connection = signal.connect(function);
// ...
signal.disconnect(connection);
Prevent function from being called anymore.
signal.connect_oneshot(function);
Like connect but function will be disconnected as soon as it has been called once.
