Multi Prompt

[macmichael01]

It would be nice to have a multi prompt similar in some ways to the form prompt but with a couple minor differences.

First, render the actual registered prompts for validation purposes. (which I don't think forms supports that but might be nice if it did too).

Second, the purpose of multi prompt is to re-ask the same questions over until the user indicates they are finished. This would be great for populating an array of objects.

E.g -
Contributors:

• Full Name:
• Email:
• Website:
  Would you like to add another (Y/n)?

The end result might look something like the following:

{
  contributors: [{
    full_name: "jon",
    email: 'jon@enquirer.com',
    website: 'enquirer.com'
  },{
    full_name: "jon",
    email: 'jon@enquirer.com',
    website: 'enquirer.com'
  }]
}

@macmichael01 I think both of your requests possible now.

Request 1 - Validating form choices

The Form prompt supports validation. If you aren't able to get it working, then please create a bug report so we can see what's causing problems for you and get it fixed. See this example.

In the choice objects, you can add a validate() function.

Request 2 - Re-asking the same questions

You should be able to accomplish this by simply wrapping your prompt in a function, and recursively calling the function if the user gives a truthy response. Let us know if you have trouble getting this to work. If I'm not understanding your request, then it might help to provide a more detailed example, possible a mockup of the screen so that I can visualize what you mean (I'm a visual learner, and I have a much harder time understanding verbally. Thanks in advance!)
