Overview

As seen in Flexo::Dispatcher. This is the class that’s spawned to handle a subscription to an event.

Each call to Flexo::Dispatcher.subscribe creates an instance of Flexo::Handler, which is called when the event fires.

Also, to unsubscribe, the original handle-object is required. So don’t throw it away.
