Discussion: Allowable card-types

[robrez]

I would like to be able to incorporate 'allowable cardType(s)' into the validation routine.

My first instinct was to set card-type to a specific value. (I think card-type should be flagged as readOnly: true).

I was considering something like this...

var opts = { amex: true, visa: true };
or
var opts = [ 'amex', 'visa' ];
...
<gold-cc-input card-types="[[opts]]">

And then patching the validate function..

        var valid = result.valid && result.length_valid;
        this.cardType = valid ? result.card_type.name : '';
+       if (valid && this.cardTypes !== null && this.cardTypes.length > 0) {
+         valid = this.cardTypes.indexOf(this.cardType) !== -1;  //or .includes()?
+       }

Any thoughts? Edit: I'm thinking cardType should be empty if invalid.

I think this is a great idea! (I left a comment on your PR, but it's almost ready to merge)
