## Introduction

Event is a simple locking primitives which allows for sending notifications 

across goroutines when an event has occurred.

## Example

```go

package main

import (

	"fmt"

	"sync"

	"time"

	

	"github.com/pkg/errors"

	"github.com/trivigy/event"

)

func main() {

	mutex := sync.Mutex{}

    	results := make([]error, 0)

    

    	start := sync.WaitGroup{}

    	finish := sync.WaitGroup{}

    	

    	N := 5

    	start.Add(N)

    	finish.Add(N)

    	for i := 0; i < N; i++ {

    		go func() {

    			start.Done()

    			

    			value := event.Wait(nil)

    			mutex.Lock()

    			results = append(results, value)

    			mutex.Unlock()

    

    			finish.Done()

    		}()

    	}

    

    	start.Wait()

    	time.Sleep(100 * time.Millisecond)

    	event.Set()

    	finish.Wait()

    	

    	fmt.Printf("%+v\n", results)

}

```
