##<paper-radio-group>

Material design: [Radio button](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-radio-button)

`paper-radio-group` allows user to select at most one radio button from a set.
Checking one radio button that belongs to a radio group unchecks any
previously checked radio button within the same group. Use
`selected` to get or set the selected radio button.

The  inside the group must have the `name` attribute
set.

Example:

```html

  Small
  Medium
  Large

```

Radio-button-groups can be made optional, and allow zero buttons to be selected:

```html

  Small
  Medium
  Large

```

See paper-radio-button for more
information about `paper-radio-button`.
