## Example interaction

Code like this:

```go

actor := interact.NewActor(os.Stdin, os.Stdout)

message := "Please enter something that's not empty"

notEmpty, err := actor.Prompt(message, checkNotEmpty)

if err != nil {

  log.Fatal(err)

}

message = "Please enter a positive number"

n1, err := actor.PromptAndRetry(message, checkNotEmpty, checkIsAPositiveNumber)

if err != nil {

  log.Fatal(err)

}

message = "Please enter another positive number"

n2, err := actor.PromptOptionalAndRetry(message, "7", checkNotEmpty, checkIsAPositiveNumber)

if err != nil {

  log.Fatal(err)

}

fmt.Printf("Thanks! (%s, %s, %s)\n", notEmpty, n1, n2)

```

Can create an interaction like this:
