interface souce {
  register(address: string, subscription: function): void;
  register(subscription: function): void;
  register({ delegate: function }): void;

address: string must start with "/".

let publisher = new Dispatcher();
let subscriber = new Dispatcher.Delegator();

// define action of address
subscriber["/message/view"] = (message) => {
  console.log(`received: ${message}`);
};

publisher.register(subscriber);

publisher.dispatch("/message/view", "hello!");
// -> call subscriber.delegate("/message/view", "hello!")
// => "received: hello!"
