support binding of a group of radio buttons to a variable

[marycampione]

How do you bind a group of radio buttons to a single variable and give each radio button a value?

<input value="{{theData['catOrDog']}}" name="catOrDog" type="radio">Cat <input value="{{theData['catOrDog']}}" name="catOrDog" type="radio">Dog <input value="{{theData['catOrDog']}}" name="catOrDog" type="radio">Iguana

Essentially we need something on par with http://docs.angularjs.org/api/ng.directive:input.radio, and MDV does not currently have this.

i made a jsbin which pairs radio buttons to checkboxes; selecting a new radio button does not deselect the previous button's paired checkbox

Unfortunately, we can't make this a concern of MDV because it's a fundamental deficit of input elements.

There are some good ways to approach this at the Polymer level:
