npm install ask-once> Only ask a question one time and store the answer.

``sh`
$ npm i ask-once --save
`js`
var ask = require('ask-once')();
Ask a question
`js`
ask.once('May I have your username?', function (err, answer) {

});
The user's answer is saved, and the question won't be asked again unless:

* the answer is deleted directly
Where are the answers stored?
The user's answers are saved on a global config store that is uniquely identified to the application using ask-once.
Can I change where answers are stored?
Yes, you can pass the name of a data-store with the cwd option set to whatever you want it to be. Here's an example:
`js
// pass the name of a data-store, so you can use
// whatever storage location you want
var ask = require('ask-once')({
store: {
name: 'foo',
cwd: 'bar'
}
});
ask.once('May I have your username?' function (err, answer) {
console.log(answer);
});
`
