-`paper-radio-group` allows user to select only 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.
-
-Example:
-
-    <paper-radio-group selected="small">
-      <paper-radio-button name="small" label="Small"></paper-radio-button>
-      <paper-radio-button name="medium" label="Medium"></paper-radio-button>
-      <paper-radio-button name="large" label="Large"></paper-radio-button>
-    </paper-radio-group>
-
-See <a href="paper-radio-button.html">paper-radio-button</a> for more
-information about `paper-radio-button`.
