## <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 `` elements inside the group must have the `name`
attribute set.
