Hello!

Thank you for your hard work!

I want to propose a feature to list fields of the form.

Right now we can access individual form fields using form[fieldName] expression. However, form controller has a lot of properties and methods, so it's not possible to iterate the list of form fields directly.

I have to use this code to iterate all fields of the form:

var fields = ['firstName', 'lastName', 'email'];
angular.forEach(fields, function (fieldName) {
  var field = form[fieldName];
  // ...
});

However, it's a bad practice to hardcode array of field names this way.

The proposed API will allow us to do something like this:

angular.forEach(form.$fields, function (field) {
  // ...
});

The other workaround is to iterate all properties of the form controller and detect ngModel objects, however it is also somewhat ugly.

I hope it makes sense. Thank you!
