[nvnamsss]

Need a module for event-drivent pattern in Go.

Event is designing as a struct, the basic Event has a list of callback and a variable determine the style of trigger

type Event struct {
    Async     bool
    callbacks map[string]func()
}

Methods:

• Subscribe(callback func()): Subscribe the callback function
• Unsubscribe(callback func()): Unsubscribe the callback function if it been subscribed
• Invoke()": Trigger all subscribed callbacks. If trigger type is async, all subscribed callback will run by goroutine. Otherwise, it will be sequentially run
