Event/Action

[dexterurbane]

We used to be able to do stuff like this:

bus->voltageUpdated().addAction([&](){
    if (abs(bus->voltage()(0)) < threshold)
    appliance->setOn(false);});

With changes that occurred some time ago, this becomes harder. For example, the action currently needs an owner, or it will go out of scope and deregister from its event.
