# limiter

A dead simple goroutine limiter.

Example:

```go

names := []string{"John", "Ada", "Merlin", "Tanya"}

// parameter is a limit

// .Start() method blocks until number 

// of running goroutines is reduced.

limit := limiter.New(2)

for _, name := range names {

    go func(name string, done func()) {

        defer done()

        fmt.Printf("Hello, %s!\n", name)

    // .Start()) blocks f the number of workers 

    // approaches the specified limit, 

    // then waits until the number of active workers decreases.

    }(name, limit.Start())

}

// .Wait() blocks until all tasks are completed.

limit.Wait()

```
