=====

Delay goroutines at will

Rationale

---

You're notifying events, say _follow_ on users, so followed users will get

notified when someone start following them, now imagine _someone_ follows

_someother_ and, immediately after, it unfollows, you don't want to send the

notification to the supposedly followed user.

`Delay` tries to solve that problem.

It allows to *delay* event triggering defining a waiting time.

While an event is waiting to be triggered it can be updated or even cancelled

(so it will never triggered).

Example

=====

```go

func main() {

	delayer := NewDelayer(func(key, payload string) {

		println(key, payload)

	}, 2*time.Second)

	delayer.Register("a", "Msg A")

	delayer.Register("b", "Msg B")

	delayer.Register("c", "Msg C")

	delayer.Register("c", "Msg C1")

	delayer.Register("c", "Msg C2")

	delayer.Register("c", "Msg C3")

	for {

		println(delayer.Pending(), " currently in queue")

		time.Sleep(1 * time.Second)

	}

}

```
